Thanks for the info. But at least in my case, I can't use an
IdentityDictionary, because the Associations I was using for keys were
built on the fly, and I needed equality comparison, not identity
I was actually using Association because it was an existing class with
two inst vars (holding two values and equality comparison was all the
behavior I required). I ended up wrapping my two values in an Array and
using that as the key, instead.
