Wanted: Hash Tables

[Johannes Waldmann]

Dear all, I would like to use hash tables in my Haskell programs
(especially in places where I use `FiniteMap String a' now).
I remember there was a  `class Hash'  in hbc (?)
and I imagine this should be combined with  STArray  or the like.
Is there already some re-usable code for doing this? Thanks -
