Isn't Cedrick's aida solution going to be significantly faster?
No, solutions based on #become: are the slowest possible. The VM has to
sweep the whole memory, for all variables in the system, to find all
references during #become:, like this
| oop |
oop := self someObject.
["check+replace reference in variables of oop, then"
oop := oop nextObject.
oop = 0
] whileFalse.
Now think that you (and every other user of your software ;-) have an
.image with 2-4gigs every time you use #become: ...
If you want something faster, look at Bert's
myCollection removeAllSuchThat: [:each | true]
and try to make it faster but keep still it correct (old elements must be
nil'ed).

Hi Sophie,
aCollection copy do: [:anElement |
aCollection remove: anElement
].
Why copy? If you start removing items from the collection, increasing
the
index will cause you to skip elements.
