The Data.HashTable included with GHC probably shouldn't be. In
practice, Data.Map outperforms it in essentially all cases
(Data.HashTable stops working beyond a certain size and so any
asymptotic benefits, if they exist at all, don't have time to kick
in). Moreover, Data.Map has a nice pure interface. The finite maps
provided by Data.Map are not actually hash tables, but instead binary
balanced trees, but who really cares? :)
