Hi Randal, none of my proxies can understand #hash.  I didn't want to have to
deal with knowing which Sets to rehash.

>From my understanding of what Bob said, every object in Squeak is represented
by a "buffer" in memory, which holds information about it.  It's class pointer,
its instance variable pointers, and its identityHash value.

Well, when you tell anObject to becomeForward: anotherObject, anotherObject
seems to be getting its identityHash value changed.  I consider this a real
problem because it is effectively changing the object-identity of the target
object.  Only the RECEIVER is supposed to have its identity changed.

And the identity of any Symbol should *never* change within the same image
session.
