[squeak-dev] Silly question: How do I make a cache registry

Hey!
Say I want to keep a Dictionary with say UUIDs as keys and objects as
values. And I hand out the UUIDs to an external program as "object
handles". But if an object gets garbage collected I want the registry to
loose that association. How?
WeakValueDictionary only looses the value, not the whole entry.
Sure, I can use finalization etc, but shouldn't there be a
WeakDictionary that can do this?
regards, Göran
