I don't think anyone has ever asked for a "pure" version of the
hashtable. (It could be frozen and thawed in the same fashion as
Arrays are). Maybe someone has written something like that and is
willing to share?

On the other hand, it's entirely possible that you can get away with
either Data.Map or saying within the IO monad.
