+"Persistent vectors support the immutable sequence protocol, namely as " { $link length } " and " { $link nth } ", and so can be used with most sequence words (" { $link "sequences" } ")."

+"In addition to standard sequence operations, persistent vectors implement efficient operations specific to them. They run in sub-linear time on persistent vectors, and degrate to linear-time algorithms on ordinary sequences:"

+"A search dequeue is a data structure with constant-time insertion and removal of elements at both ends, and constant-time membership tests. Inserting an element more than once has no effect. Search dequeues implement all dequeue operations in terms of an underlying dequeue, and membership testing with " { $link dequeue-member? } " is implemented with an underlying assoc. Search dequeues are defined in the " { $vocab-link "search-dequeues" } " vocabulary."

Subject: [PATCH 0186/1850] Refactor windows.com.wrapper to make better use of
 fry and cleave to show what is going on. Create named words for wrapper
 alien-callbacks so it is easy to see what code gets generated. Change
 com-query-interface to malloc the buffer for the returned interface pointer
 to avoid GC heisenbugs when calling into a com-wrapped factor object

+#! The interesting thing about this parser is the mixing of
+#! a default and non-default tokenizer. The JavaScript tokenizer
+#! removes all newlines. So when operating on tokens there is no
+#! need for newline and space skipping in the grammar. But JavaScript
+#! uses the newline in the 'automatic semicolon insertion' rule. 
+#!
+#! If a statement ends in a newline, sometimes the semicolon can be
+#! skipped. So we define an 'nl' rule using the default tokenizer. 
+#! This operates a character at a time. Using this 'nl' in the parser
+#! allows us to detect newlines when we need to for the semicolon
+#! insertion rule, but ignore it in all other places.

+ARTICLE: "slot-class-coercion" "Coercive slot declarations"
+"If the class of a slot is declared to be one of " { $link fixnum } " or " { $link float } ", then rather than testing values with the class predicate, writer words coerce values to the relevant type with " { $link >fixnum } " or " { $link >float } ". This may still result in error, but permits a wider range of values than a class predicate test. It also results in a possible loss of precision; for example, storing a large integer into a " { $link fixnum } " slot will silently overflow and discard high bits, and storing a ratio into a " { $link float } " slot may lose precision if the ratio is one which cannot be represented exactly with floating-point."

+/* Simple non-optimizing compiler.
+
+This is one of the two compilers implementing Factor; the second one is written
+in Factor and performs advanced optimizations. See core/compiler/compiler.factor.
+
+The non-optimizing compiler compiles a quotation at a time by concatenating
+machine code chunks; prolog, epilog, call word, jump to word, etc. These machine
+code chunks are generated from Factor code in core/cpu/.../bootstrap.factor.
+
+It actually does do a little bit of very simple optimization:
+
+1) Tail call optimization.
+
+2) If a quotation is determined to not call any other words (except for a few
+special words which are open-coded, see below), then no prolog/epilog is
+generated.
+
+3) When in tail position and immediately preceded by literal arguments, the
+'if' and 'dispatch' conditionals are generated inline, instead of as a call to
+the 'if' word.
+
+4) When preceded by an array, calls to the 'declare' word are optimized out
+entirely. This word is only used by the optimizing compiler, and with the
+non-optimizing compiler it would otherwise just decrease performance to have to
+push the array and immediately drop it after.
+
+5) Sub-primitives are primitive words which are implemented in assembly and not
+in the VM. They are open-coded and no subroutine call is generated. This
+includes stack shufflers, some fixnum arithmetic words, and words such as tag,
+slot and eq?. A primitive call is relatively expensive (two subroutine calls)
+so this results in a big speedup for relatively little effort.

If you need more fine grained control then do the following: First annotate individual words with the " { $link add-timer } " word or whole vocabularies with " { $link add-timers } ". Then reset the clock with " { $link reset-word-timer } " and execute your code. Finally you can view the timings with " { $link print-word-timings } ". If you have functions that are quick and called often you may want to " { $link correct-for-timing-overhead } ". To remove all the annotations in the vocab you can use " { $link reset-vocab } ". Alternatively if you just want to time the contents of a vocabulary you can use profile-vocab." ;

+ARTICLE: "specializers" "Word specializers"
+"The optimizer can be passed hints as to the classes of parameters a word is expected to be called with. The optimizer will then generate multiple versions of word when compiling, specialized to each class."
+$nl
+"Specialization hints are stored in the " { $snippet "\"specializer\"" } " word property. The value of this property is either a sequence of classes, or a sequence of sequences of classes. Each element in the sequence (or the sequence itself, in the former case) is a specialization hint."
+$nl
+"Specialization can help in the case where a word calls a lot of generic words on the same object - perhaps in a loop - and in most cases, it is anticipated that this object is of a certain class. Using specialization hints, the compiler can be instructed to compile a branch at the beginning of the word; if the branch is taken, the input object has the assumed class, and inlining of generic methods can take place."
+$nl
+"Specialization hints are not declarations; if the inputs do not match what is specified, the word will still run, possibly slower if the compiled code cannot inline methods because of insufficient static type information."
+$nl
+"In some cases, specialization will not help at all, and can make generated code slower from the increase in code size. The compiler is capable of inferring enough static type information to generate efficient code in many cases without explicit help from the programmer. Specializers should be used as a last resort, after profiling shows that a critical loop makes a lot of repeated calls to generic words which dispatch on the same class."
+$nl
+"For example, the " { $link append } " word has a specializer for the very common case where two strings or two arrays are appended:"
+{ $code
+"\\ append"
+"{ { string string } { array array } }"
+"\"specializer\" set-word-prop"

+ARTICLE: "inference-simple" "Straight-line stack effects"
+"The simplest case to look at is that of a quotation which does not have any branches or recursion, and just pushes literals and calls words, each of which has a known stack effect."
+$nl
+"Stack effect inference works by stepping through the quotation, while maintaining a \"shadow stack\" which tracks stack height at the current position in the quotation. Initially, the shadow stack is empty. If a word is encountered which expects more values than there are on the shadow stack, a global counter is incremented. This counter keeps track of the number of inputs the quotation expects on the stack. When inference is done, this counter, together with the final height of the shadow stack, gives the inferred stack effect."
+{ $subsection d-in }
+{ $subsection meta-d }
+"When a literal is encountered, it is simply pushed on the shadow stack. For example, the stack effect of the following quotation is inferred by pushing all three literals on the shadow stack, then taking the value of " { $link d-in } " and the length of " { $link meta-d } ":"
+{ $example "[ 1 2 3 ] infer." "( -- object object object )" }
+"In the following example, the call to " { $link + } " expects two values on the shadow stack, but only one value is present, the literal which was pushed previously. This increments the " { $link d-in } " counter by one:"
+{ $example "[ 2 + ] infer." "( object -- object )" }
+"After the call to " { $link + } ", the shadow stack contains a \"computed value placeholder\", since the inferencer has no way to know what the resulting value actually is (in fact it is arbitrary)." ;
+
+ARTICLE: "inference-combinators" "Combinator stack effects"
+"Without further information, one cannot say what the stack effect of " { $link call } " is; it depends on the given quotation. If the inferencer encounters a " { $link call } " without further information, a " { $link literal-expected } " error is raised."
+{ $example "[ dup call ] infer." "... an error ..." }
+"On the other hand, the stack effect of applying " { $link call } " to a literal quotation or a " { $link curry } " of a literal quotation is easy to compute; it behaves as if the quotation was substituted at that point:"
+{ $example "[ [ 2 + ] call ] infer." "( object -- object )" }
+"Consider a combinator such as " { $link keep } ". The combinator itself does not have a stack effect, because it applies " { $link call } " to a potentially arbitrary quotation. However, since the combinator is declared " { $link POSTPONE: inline } ", a given usage of it can have a stack effect:"
+{ $example "[ [ 2 + ] keep ] infer." "( object -- object object )" }
+"Another example is the " { $link compose } " combinator. Because it is decared " { $link POSTPONE: inline } ", we can infer the stack effect of applying " { $link call } " to the result of " { $link compose } ":"
+{ $example "[ 2 [ + ] curry [ sq ] compose ] infer." "( -- object object )" }
+"Incidentally, this example demonstrates that the stack effect of nested currying and composition can also be inferred."
+$nl
+"A general rule of thumb is that any word which applies " { $link call } " or " { $link curry } " to one of its inputs must be declared " { $link POSTPONE: inline } "."
+$nl
+"Here is an example where the stack effect cannot be inferred:"
+{ $code ": foo 0 [ + ] ;" "[ foo reduce ] infer." }
+"However if " { $snippet "foo" } " was declared " { $link POSTPONE: inline } ", everything would work, since the " { $link reduce } " combinator is also " { $link POSTPONE: inline } ", and the inferencer can see the literal quotation value at the point it is passed to " { $link call } ":"
+{ $example ": foo 0 [ + ] ; inline" "[ foo reduce ] infer." "( object -- object )" } ;
+
+ARTICLE: "inference-branches" "Branch stack effects"
+"Conditionals such as " { $link if } " and combinators built on " { $link if } " present a problem, in that if the two branches leave the stack at a different height, it is not clear what the stack effect should be. In this case, inference throws a " { $link unbalanced-branches-error } "."
+$nl
+"If all branches leave the stack at the same height, then the stack effect of the conditional is just the maximum of the stack effect of each branch. For example,"
+{ $example "[ [ + ] [ drop ] if ] infer." "( object object object -- object )" }
+"The call to " { $link if } " takes one value from the stack, a generalized boolean. The first branch " { $snippet "[ + ]" } " has stack effect " { $snippet "( x x -- x )" } " and the second has stack effect " { $snippet "( x -- )" } ". Since both branches decrease the height of the stack by one, we say that the stack effect of the two branches is " { $snippet "( x x -- x )" } ", and together with the boolean popped off the stack by " { $link if } ", this gives a total stack effect of " { $snippet "( x x x -- x )" } "." ;
+
+ARTICLE: "inference-recursive" "Stack effects of recursive words"
+"Recursive words must declare a stack effect. When a recursive call is encountered, the declared stack effect is substituted in. When inference is complete, the inferred stack effect is compared with the declared stack effect."
+$nl
+"Attempting to infer the stack effect of a recursive word which outputs a variable number of objects on the stack will fail. For example, the following will throw an " { $link unbalanced-branches-error } ":"
+{ $code ": foo ( seq -- ) dup empty? [ drop ] [ dup pop foo ] if" "[ foo ] infer." }
+"If you declare an incorrect stack effect, inference will fail also. Badly defined recursive words cannot confuse the inferencer." ;
+
+ARTICLE: "inference-limitations" "Inference limitations"
+"Mutually recursive words are supported, but mutually recursive " { $emphasis "inline" } " words are not."
+$nl
+"An inline recursive word cannot pass a quotation through the recursive call. For example, the following will not infer:"
+{ $code ": foo ( a b c -- d e f ) [ f foo drop ] when 2dup call ; inline" "[ 1 [ 1+ ] foo ] infer." }
+"However a small change can be made:"
+{ $example ": foo ( a b c -- d ) [ 2dup f foo drop ] when call ; inline" "[ 1 [ 1+ ] t foo ] infer." "( -- object )" }
+"An inline recursive word must have a fixed stack effect in its base case. The following will not infer:"
+{ $code
+    ": foo ( quot ? -- ) [ f foo ] [ call ] if ; inline"
+    "[ [ 5 ] t foo ] infer."
+} ;
+
+ARTICLE: "compiler-transforms" "Compiler transforms"
+"Compiler transforms can be used to allow words to compile which would otherwise not have a stack effect, and to expand combinators into more efficient code at compile time."
+{ $subsection define-transform }
+"An example is the " { $link cond } " word. If the association list of quotations it is given is literal, the entire form is expanded into a series of nested calls to " { $link if } "."
+$nl
+"The " { $vocab-link "macros" } " vocabulary defines some nice syntax sugar which makes compiler transforms easier to work with." ;
+
+ARTICLE: "inference" "Stack effect inference"
+"The stack effect inference tool is used to check correctness of code before it is run. It is also used by the optimizing compiler to build the high-level SSA representation on which optimizations can be performed. Only words for which a stack effect can be inferred will compile with the optimizing compiler; all other words will be compiled with the non-optimizing compiler (see " { $link "compiler" } ")."
+$nl
+"The main entry point is a single word which takes a quotation and prints its stack effect and variable usage:"
+{ $subsection infer. }
+"Instead of printing the inferred information, it can be returned as objects on the stack:"
+{ $subsection infer }
+"Static stack effect inference can be combined with unit tests; see " { $link "tools.test.write" } "."

+{ $values { "word" word } { "quot" "a quotation taking " { $snippet "n" } " inputs from the stack and producing another quotation as output" } { "n" "a non-negative integer" } }
+{ $description "Defines a compiler transform for the optimizing compiler. When a call to " { $snippet "word" } " is being compiled, the compiler ensures that the top " { $snippet "n" } " stack values are literal; if they are not, compilation fails. The literal values are passed to the quotation, which is expected to produce a new quotation. The call to the word is then replaced by this quotation." }
+{ $examples "Here is a word which pops " { $snippet "n" } " values from the stack:"
+{ $code ": ndrop ( n -- ) [ drop ] times ;" }
+"This word is inefficient; it does not have a static stack effect. This means that words calling " { $snippet "ndrop" } " cannot be compiled by the optimizing compiler, and additionally, a call to this word will always involve a loop with arithmetic, even if the value of " { $snippet "n" } " is known at compile time. A compiler transform can fix this:"
+{ $code "\\ ndrop [ \\ drop <repetition> >quotation ] 1 define-transform" }
+"Now, a call like " { $snippet "4 ndrop" } " is replaced with " { $snippet "drop drop drop drop" } " at compile time; the optimizer then ensures that this compiles as a single machine instruction, which is a lot cheaper than an actual call to " { $snippet "ndrop" } "."
+$nl
+"The " { $link cond } " word compiles to efficient code because it is transformed using " { $link cond>quot } ":"
+{ $code "\\ cond [ cond>quot ] 1 define-transform" } } ;

+
+! DESCRIPTION
+! -----------
+
+! A printing shop runs 16 batches (jobs) every week and each batch requires a
+! sheet of special colour-proofing paper of size A5.
+
+! Every Monday morning, the foreman opens a new envelope, containing a large
+! sheet of the special paper with size A1.
+
+! He proceeds to cut it in half, thus getting two sheets of size A2. Then he
+! cuts one of them in half to get two sheets of size A3 and so on until he
+! obtains the A5-size sheet needed for the first batch of the week.
+
+! All the unused sheets are placed back in the envelope.
+
+! At the beginning of each subsequent batch, he takes from the envelope one
+! sheet of paper at random. If it is of size A5, he uses it. If it is larger,
+! he repeats the 'cut-in-half' procedure until he has what he needs and any
+! remaining sheets are always placed back in the envelope.
+
+! Excluding the first and last batch of the week, find the expected number of
+! times (during each week) that the foreman finds a single sheet of paper in
+! the envelope.
+
+! Give your answer rounded to six decimal places using the format x.xxxxxx .

-ARTICLE: "inference-simple" "Straight-line stack effects"
-"The simplest case to look at is that of a quotation which does not have any branches or recursion, and just pushes literals and calls words, each of which has a known stack effect."
-$nl
-"Stack effect inference works by stepping through the quotation, while maintaining a \"shadow stack\" which tracks stack height at the current position in the quotation. Initially, the shadow stack is empty. If a word is encountered which expects more values than there are on the shadow stack, a global counter is incremented. This counter keeps track of the number of inputs the quotation expects on the stack. When inference is done, this counter, together with the final height of the shadow stack, gives the inferred stack effect."
-{ $subsection d-in }
-{ $subsection meta-d }
-"When a literal is encountered, it is simply pushed on the shadow stack. For example, the stack effect of the following quotation is inferred by pushing all three literals on the shadow stack, then taking the value of " { $link d-in } " and the length of " { $link meta-d } ":"
-{ $example "[ 1 2 3 ] infer." "( -- object object object )" }
-"In the following example, the call to " { $link + } " expects two values on the shadow stack, but only one value is present, the literal which was pushed previously. This increments the " { $link d-in } " counter by one:"
-{ $example "[ 2 + ] infer." "( object -- object )" }
-"After the call to " { $link + } ", the shadow stack contains a \"computed value placeholder\", since the inferencer has no way to know what the resulting value actually is (in fact it is arbitrary)." ;
-
-ARTICLE: "inference-combinators" "Combinator stack effects"
-"Without further information, one cannot say what the stack effect of " { $link call } " is; it depends on the given quotation. If the inferencer encounters a " { $link call } " without further information, a " { $link literal-expected } " error is raised."
-{ $example "[ dup call ] infer." "... an error ..." }
-"On the other hand, the stack effect of applying " { $link call } " to a literal quotation or a " { $link curry } " of a literal quotation is easy to compute; it behaves as if the quotation was substituted at that point:"
-{ $example "[ [ 2 + ] call ] infer." "( object -- object )" }
-"Consider a combinator such as " { $link keep } ". The combinator itself does not have a stack effect, because it applies " { $link call } " to a potentially arbitrary quotation. However, since the combinator is declared " { $link POSTPONE: inline } ", a given usage of it can have a stack effect:"
-{ $example "[ [ 2 + ] keep ] infer." "( object -- object object )" }
-"Another example is the " { $link compose } " combinator. Because it is decared " { $link POSTPONE: inline } ", we can infer the stack effect of applying " { $link call } " to the result of " { $link compose } ":"
-{ $example "[ 2 [ + ] curry [ sq ] compose ] infer." "( -- object object )" }
-"Incidentally, this example demonstrates that the stack effect of nested currying and composition can also be inferred."
-$nl
-"A general rule of thumb is that any word which applies " { $link call } " or " { $link curry } " to one of its inputs must be declared " { $link POSTPONE: inline } "."
-$nl
-"Here is an example where the stack effect cannot be inferred:"
-{ $code ": foo 0 [ + ] ;" "[ foo reduce ] infer." }
-"However if " { $snippet "foo" } " was declared " { $link POSTPONE: inline } ", everything would work, since the " { $link reduce } " combinator is also " { $link POSTPONE: inline } ", and the inferencer can see the literal quotation value at the point it is passed to " { $link call } ":"
-{ $example ": foo 0 [ + ] ; inline" "[ foo reduce ] infer." "( object -- object )" } ;
-
-ARTICLE: "inference-branches" "Branch stack effects"
-"Conditionals such as " { $link if } " and combinators built on " { $link if } " present a problem, in that if the two branches leave the stack at a different height, it is not clear what the stack effect should be. In this case, inference throws a " { $link unbalanced-branches-error } "."
-$nl
-"If all branches leave the stack at the same height, then the stack effect of the conditional is just the maximum of the stack effect of each branch. For example,"
-{ $example "[ [ + ] [ drop ] if ] infer." "( object object object -- object )" }
-"The call to " { $link if } " takes one value from the stack, a generalized boolean. The first branch " { $snippet "[ + ]" } " has stack effect " { $snippet "( x x -- x )" } " and the second has stack effect " { $snippet "( x -- )" } ". Since both branches decrease the height of the stack by one, we say that the stack effect of the two branches is " { $snippet "( x x -- x )" } ", and together with the boolean popped off the stack by " { $link if } ", this gives a total stack effect of " { $snippet "( x x x -- x )" } "." ;
-
-ARTICLE: "inference-recursive" "Stack effects of recursive words"
-"Recursive words must declare a stack effect. When a recursive call is encountered, the declared stack effect is substituted in. When inference is complete, the inferred stack effect is compared with the declared stack effect."
-$nl
-"Attempting to infer the stack effect of a recursive word which outputs a variable number of objects on the stack will fail. For example, the following will throw an " { $link unbalanced-branches-error } ":"
-{ $code ": foo ( seq -- ) dup empty? [ drop ] [ dup pop foo ] if" "[ foo ] infer." }
-"If you declare an incorrect stack effect, inference will fail also. Badly defined recursive words cannot confuse the inferencer." ;
-
-ARTICLE: "inference-limitations" "Inference limitations"
-"Mutually recursive words are supported, but mutually recursive " { $emphasis "inline" } " words are not."
-$nl
-"An inline recursive word cannot pass a quotation through the recursive call. For example, the following will not infer:"
-{ $code ": foo ( a b c -- d e f ) [ f foo drop ] when 2dup call ; inline" "[ 1 [ 1+ ] foo ] infer." }
-"However a small change can be made:"
-{ $example ": foo ( a b c -- d ) [ 2dup f foo drop ] when call ; inline" "[ 1 [ 1+ ] t foo ] infer." "( -- object )" }
-"An inline recursive word must have a fixed stack effect in its base case. The following will not infer:"

-ARTICLE: "compiler-transforms" "Compiler transforms"

-"Further customization can be achieved by hooking into the lower-level machinery used by " { $link define-transform } ", the " { $snippet "\"infer\"" } " word property."

-{ $description "Defines a compiler transform for the optimizing compiler. When a call to " { $snippet "word" } " is being compiled, the compiler ensures that the top " { $snippet "n" } " stack values are literal; if they are not, compilation fails. The literal values are passed to the quotation, which is expected to produce a new quotation. The call to the word is then replaced by this quotation." }
-{ $examples "Here is a word which pops " { $snippet "n" } " values from the stack:"
-{ $code ": ndrop ( n -- ) [ drop ] times ;" }
-"This word is inefficient; it does not have a static stack effect. This means that words calling " { $snippet "ndrop" } " cannot be compiled by the optimizing compiler, and additionally, a call to this word will always involve a loop with arithmetic, even if the value of " { $snippet "n" } " is known at compile time. A compiler transform can fix this:"
-{ $code "\\ ndrop [ \\ drop <repetition> >quotation ] 1 define-transform" }
-"Now, a call like " { $snippet "4 ndrop" } " is replaced with " { $snippet "drop drop drop drop" } " at compile time; the optimizer then ensures that this compiles as a single machine instruction, which is a lot cheaper than an actual call to " { $snippet "ndrop" } "."
-$nl
-"The " { $link cond } " word compiles to efficient code because it is transformed using " { $link cond>quot } ":"

-"The optimizer can be passed hints as to the classes of parameters a word is expected to be called with. The optimizer will then generate multiple versions of word when compiling, specialized to each class."
-$nl
-"Specialization hints are stored in the " { $snippet "\"specializer\"" } " word property. The value of this property is either a sequence of classes, or a sequence of sequences of classes. Each element in the sequence (or the sequence itself, in the former case) is a specialization hint."
-$nl
-"Specialization can help in the case where a word calls a lot of generic words on the same object - perhaps in a loop - and in most cases, it is anticipated that this object is of a certain class. Using specialization hints, the compiler can be instructed to compile a branch at the beginning of the word; if the branch is taken, the input object has the assumed class, and inlining of generic methods can take place."
-$nl
-"Specialization hints are not declarations; if the inputs do not match what is specified, the word will still run, possibly slower if the compiled code cannot inline methods because of insufficient static type information."
-$nl
-"In some cases, specialization will not help at all, and can make generated code slower from the increase in code size. The compiler is capable of inferring enough static type information to generate efficient code in many cases without explicit help from the programmer. Specializers should be used as a last resort, after profiling shows that a critical loop makes a lot of repeated calls to generic words which dispatch on the same class."
-$nl
-"For example, the " { $link append } " word has a specializer for the very common case where two strings or two arrays are appended:"

+"A search deque is a data structure with constant-time insertion and removal of elements at both ends, and constant-time membership tests. Inserting an element more than once has no effect. Search deques implement all deque operations in terms of an underlying deque, and membership testing with " { $link deque-member? } " is implemented with an underlying assoc. Search deques are defined in the " { $vocab-link "search-deques" } " vocabulary."

-ARTICLE: "specializers" "Word specializers"
-"The optimizer can be passed hints as to the classes of parameters a word is expected to be called with. The optimizer will then generate multiple versions of word when compiling, specialized to each class."
-$nl
-"Specialization hints are stored in the " { $snippet "\"specializer\"" } " word property. The value of this property is either a sequence of classes, or a sequence of sequences of classes. Each element in the sequence (or the sequence itself, in the former case) is a specialization hint."
-$nl
-"Specialization can help in the case where a word calls a lot of generic words on the same object - perhaps in a loop - and in most cases, it is anticipated that this object is of a certain class. Using specialization hints, the compiler can be instructed to compile a branch at the beginning of the word; if the branch is taken, the input object has the assumed class, and inlining of generic methods can take place."
-$nl
-"Specialization hints are not declarations; if the inputs do not match what is specified, the word will still run, possibly slower if the compiled code cannot inline methods because of insufficient static type information."
-$nl
-"In some cases, specialization will not help at all, and can make generated code slower from the increase in code size. The compiler is capable of inferring enough static type information to generate efficient code in many cases without explicit help from the programmer. Specializers should be used as a last resort, after profiling shows that a critical loop makes a lot of repeated calls to generic words which dispatch on the same class."
-$nl
-"For example, the " { $link append } " word has a specializer for the very common case where two strings or two arrays are appended:"
-{ $code
-"\\ append"

+ARTICLE: "hints" "Compiler specialization hints"
+"Specialization hints help the compiler generate efficient code."
+$nl
+"Specialization hints can help words which call a lot of generic words on the same object - perhaps in a loop - and in most cases, it is anticipated that this object is of a certain class. Using specialization hints, the compiler can be instructed to compile a branch at the beginning of the word; if the branch is taken, the input object has the assumed class, and inlining of generic methods can take place."
+$nl
+"Specialization hints are not declarations; if the inputs do not match what is specified, the word will still run, possibly slower if the compiled code cannot inline methods because of insufficient static type information."
+$nl
+"In some cases, specialization will not help at all, and can make generated code slower from the increase in code size. The compiler is capable of inferring enough static type information to generate efficient code in many cases without explicit help from the programmer. Specializers should be used as a last resort, after profiling shows that a critical loop makes a lot of repeated calls to generic words which dispatch on the same class."

 ARTICLE: "locals-limitations" "Limitations of locals"
 "The first limitation is that the " { $link >r } " and " { $link r> } " words may not be used together with locals. Instead, use the " { $link dip } " combinator."
 $nl
-"Another limitation is that closure conversion does not descend into arrays, hashtables or other types of literals. For example, the following does not work:"
+"Another limitation concerns combinators implemented as macros. Locals can only be used with such combinators if the input array immediately precedes the combinator call. For example, the following will work:"
 { $code
-    ":: bad-cond-usage ( a -- ... )"
+    ":: good-cond-usage ( a -- ... )"
     "    {"
     "        { [ a 0 < ] [ ... ] }"
     "        { [ a 0 > ] [ ... ] }"

+    "        { [ a 0 = ] [ ... ] }"
+    "    } my-cond ;"
+}
+"The reason is that locals are rewritten into stack code at parse time, whereas macro expansion is performed later during compile time. To circumvent this problem, the " { $vocab-link "macros.expander" } " vocabulary is used to rewrite simple macro usages prior to local transformation, however "{ $vocab-link "macros.expander" } " does not deal with more complicated cases where the literal inputs to the macro do not immediately precede the macro call in the source." ;
 
 ARTICLE: "locals" "Local variables and lexical closures"
 "The " { $vocab-link "locals" } " vocabulary implements lexical scope with full closures, both downward and upward. Mutable bindings are supported, including assignment to bindings in outer scope."

The language semantics, user interface, and implementation each help create this integrated experience. The language semantics embed the programmer in a uniform world of simple ob jects that can be modified without appealing to definitions of abstractions. In a similar way, the graphical interface puts the user into a uniform world of tangible objects that can be directly manipulated and changed without switching modes. The implementation strives to support the world-of-objects illusion by minimiz ing perceptible pauses and by providing true source-level semantics without sac rificing performance. As a side benefit, it encourages factoring. Although we see areas that fall short of the vision, on the whole, the language, interface, and im plementation conspire so that the Self programmer lives and acts in a consistent and malleable world of objects."

Prototypes combine inheritance and instantiation to provide a framework that is simpler and more flexible than most object-oriented languages. Slots unite variables and procedures into a single construct. This permits the inheritance hierarchy to take over the function of lexical scoping in conventional languages. Finally, because Self does not distinguish state from behavior, it narrows the gaps between ordinary objects, procedures, and closures. Self's simplicity and expressiveness offer new insights into object-oriented computation."

The programmer resolves ambiguities arising from multiple inheritance by prioritizing an object's parents. Unifying unordered and ordered multiple inheritance supports differential programming of abstractions and methods, combination of unrelated abstractions, unequal combination of abstractions, and mixins. In Self, a private slot may be accessed if the sending method is a shared part of the receiver, allowing privileged communication between related objects. Thus, classless Self enjoys the benefits of class-based encapsulation."

A single model--dividing types into prototypes and traits--supports sharing of behavior and extending or replacing representations. A natural extension, dynamic object inheritance, can model behavioral modes. Object inheritance can also be used to provide structured name spaces for well-known objects. Classless languages can even express 'class-based' encapsulation. These stylized uses of object inheritance become instantly recognizable idioms, and extend the repertory of organizing principles to cover a wider range of programs."

+    abstract "Inspired by ACTORS [Greif and Hewitt] [Smith and Hewitt], we have implemented an interpreter for a LISP-like language, SCHEME, based on the lambda calculus [Church], but extended for side effects, multiprocessing, and process synchronization. The purpose of this implementation is tutorial. We wish to: (1) alleviate the confusion caused by Micro-PLANNER, CONNIVER, etc. by clarifying the embedding of non-recursive control structures in a recursive host language like LISP. (2) explain how to use these control structures, independent of such issues as pattern matching and data base manipulation. (3) have a simple concrete experimental domain for certain issues of programming semantics and style."

Originally conceived and developed by a single individual, its later development has progressed under two significant influences: professional programmers who developed tools to solve application problems and then commercialized them, and the interests of hobbyists concerned with free distribution of Forth. These influences have produced a language markedly different from traditional programming languages."

This system ran on two early minicomputers (a 16 KB DDP-116 and a 32 KB H316) joined by a serial link. Both a multiprogrammed system and a multiprocessor system (in that both computers shared responsibility for controlling the telescope and its scientific instruments), it was responsible for pointing and tracking the telescope, collecting data and recording it on magnetic tape, and supporting an interactive graphics terminal on which an astronomer could analyze previously recorded data. The multiprogrammed nature of the system allowed all these functions to be performed concurrently, without timing conflicts or other interference."

+! be expanded before propagation since we need to see 'fixnum?'
+! instead of 'tag 0 eq?' and so on, for semantic reasoning.
+! We also delete empty stack shuffles and copies to facilitate
+! tail call optimization in the code generator. After this pass
+! runs, stack flow information is no longer accurate, since we
+! punt in 'splice-quot' and don't update everything that we
+! should; this simplifies the code, improves performance, and we
