#become: swaps the two pointers, so both objects continue to exist. Use the asymmetric variant #becomeForward: to get rid of an object. And you probably also need a "Smalltalk garbageCollect" to make the object really disappear. Lukas 2009/12/2 Stéphane Ducasse <stephane.ducasse@inria.fr>:
become: changes the pointer pointing to the objects not the object itself. So I'm not sure that instance should be changed.
If I remember correctly what allinstances does is that it use nextObject to iterate over the object spaces.

Hi! Â Look this peace of code:
| instance | instance := TestCase new. Transcript show: TestCase allInstances size; cr. instance become: 'aString'. Transcript show: TestCase allInstances size; cr.
The size of TestCase instances is always the same. Although I used become: (and changed to an instance of another class) to one of its instances.
So, my main question is, is this correct ? Â Or the message allInstances to TestCase should not take into account the instance I sent the message become: Â ?
Thanks in advance.
