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:. |
