Why won't #chasePointers pick up the obj tempvar from the snippet above? Is this just because contexts are only married on demand?
Best,
Christoph

Hi Chris,

Which is why I don't use the pointer explorer when I'm trying to clean all instance of a class out. Instead:
TheClass allInstances anyOne chasePointers
TheClass someInstance ifNotNil: [:obj| obj chasePointers]
Ah, I will start using #someInstance, but typing ifNotNil: is a lot more work than closing a debugger when no more instances. Besides, wouldn't the Block Context's var, "obj" be another possible reference that #chasePointers might pick up on?
ifNotNil: is inlined. It is equivalent to this, but saves the temp decl, which is why it's so nice.
| obj |
obj := TheClass someInstance.
obj == nil ifFalse: [obj chasePointers]

best, Eliot
