Isn't it time to start using Weak referenes (WeakArrays,
Dictionaries,
etc) in Squeak base, where needed?

        My bigest concern is Dependencies management (DependentsFields)
and
Symbols' known Symbols collections.

        I think that using Weak references will make it easier to use
things
like that (specially references)

        Weakeable Bye!  (don't forget it!)
