become:
- Porting tip:
- The exact semantics of become: (and
Array>>multiBecome:) are not consistent across different
Smalltalk platforms, particularly in the use of the two-way become
(in which the receiver and argument actually switch identities) and the
one-way become (in which the receiver is de-referenced and garbage
collected). IBM Smalltalk uses a one-way become. See
the Blue Book for more complete information on
become:.
