Yes, that should be possible. However Squeak has inherent problems
with dictionaries having more than 4000 elements, and even worse,
with weak finalization; two things that are very likely to be needed
for an instance-based description cache.

Yes, I know GOODS, it gets very slow when the caches grow. OmniBase
uses a slightly different approach and has its own fast
implementation of an IdentityDictionary.

True, however the builder for desktop-interfaces probably needs some
more work to be useable in production ;-)
