Personally, I tend to agree that there should be a hashtable that does

SetCategory is not very important, but BasicType (that is equality)
is crucial.

I just browsed a bit through the exports of HashTable. I cannot find a real need for = for the "Entry" parameter. Maybe, I've overlooked something.

You might be right for the Axiom library, but there is conceptually no need to impose any restrictions on the Entry type as long as one doesn't expect too much in return.
