But it would be like cheating :-)
In this case, the IO method *is* cheating.

If you mean using a non-destructive map where the IO-problem is absent, that is a doable thing. But it would be like cheating :-)
What I try do do is something like:
test = do h <- HashTable.new (==) (\key -> key) h1 <- HashTable.new (==) (\key -> key) HashTable.insert h 3 h1 HashTable.insert h1 1 1000 res <- case HashTable.lookup h 3 of Nothing -> Nothing Just outer -> HashTable.lookup outer 1000 return res _______________________________________________ Haskell-Cafe mailing list Haskell-Cafe@haskell.org http://www.haskell.org/mailman/listinfo/haskell-cafe
