Tuple redefinition
In addition to the slot reader and writer words which
TUPLE:
defines for every tuple class, it is possible to construct and take apart entire tuples in a generic way.
>tuple
( seq -- tuple )
tuple>array
( tuple -- array )
tuple-slots
( tuple -- seq )
slots>tuple
( seq class -- tuple )
Tuples can be compared for slot equality even if the tuple class overrides
equal?
:
tuple=
( tuple1 tuple2 -- ? )
Tuple classes can also be defined at run time:
define-tuple-class
( class superclass slots -- )
