"By default, all slots are writable. If a slot is explicitly declared " { $link read-only } ", then no writer method is generated for the slot, and the only way to set it to a value other than its initial value is to construct an instance of the tuple with " { $link boa } ", passing the initial value for the read-only slot on the stack; the common idiom of calling " { $link new } " and then immediately filling in slot values with setter words will not work with read-only slots." ;
ARTICLE: "slot-class-declaration" "Slot class declarations"
"Class declaration is optional, and the default value is " { $link object } ", the class of all objects. If a more specific class is declared, then the object system maintains an invariant that the value of the slot must always be an instance of the class, even during construction. This invariant is enforced at a number of locations:"

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."
$nl
"This feature is mostly intended as an optimization for low-level code designed to avoid integer overflow, or where floating point precision is sufficient. Most code needs to work transparently with large integers, and thus hsould avoid the coercion behavior by using " { $link integer } " and " { $link real } " in place of " { $link fixnum } " and " { $link float } "." ;

"Note that if a slot is moved from a class to its superclass (or vice versa) in the same compilation unit, the value of the slot is preserved in existing instances, because tuple instance update always runs at the end of a compilation unit.
