 ARTICLE: "c-data" "Passing data between Factor and C"
-"Two defining characteristics of Factor are dynamic typing and automatic memory management, which are somewhat incompatible with the machine-level data model exposed by C. Factor's C library interface defines its own set of C data types, distinct from Factor language types, together with automatic conversion between Factor values and C types. For example, C integer types must be declared and are fixed-width, whereas Factor supports arbitrary-precision integers. Also Factor's garbage collector can move objects in memory, which means that special support has to be provided for passing blocks of memory to C code."

Subject: [PATCH 023/122] remove => action and replace it with [[ code ]] in
 EBNF Previously the action had to be a factor word and could only appear at
 the end of a rule:

  : aword ( ast -- ast ) drop V{ 1 2 } ;
  <EBNF foo = "a" "b" => aword EBNF>

Now actions can appear anywhere after an element, and can be any factor code between [[ ... ]] delimiters:

  <EBNF foo = "a" "b" [[ drop V{ 1 2 } ]] EBNF>
  <EBNF foo = "a" [[ drop 1 ]] "b" [[ drop 2 ]] EBNF>

Unfortunately since this means the ebnf>quot code uses the equivalent of eval, it no longer compiles nicely since it can't be inferred. The generated parsers however do compile.

Subject: [PATCH 052/122] More refactoring of EBNF <EBNF .. EBNF> now produces
 a quotation that when called does the parsing EBNF: foo ... ;EBNF creates a
 'foo' word with stack effect (string -- result) when called it parses the
 string and returns the result.

+"Since the reader and writer are generic, words can be written which do not depend on the specific class of tuple passed in, but instead work on any tuple that defines slots with certain names."

+"In most cases, using the setter is preferred over the writer because the stack effect is better suited to the common case where the tuple is needed again, and where the new slot value was just computed and so is at the top of the stack. For example, consider the case where you want to create a tuple and fill in the slots with literals. The following version uses setters:"

+    "    swap >>to"
+    "    \"alice@bigcorp.com\" >>from"
