bug?

Dear ladies and gentlemen, I'm trying to learn Haskell using Hugs. On my experiments I tried to run the Haskore example. But I get the following error: ERROR "/usr/local/share/hugs/lib/hugs/../Haskore/src/Monads.hs" (line 55): No member "map" in class "Functor" Now I looked into the Prelude and there one can just find fmap class Functor f where fmap :: (a -> b) -> (f a -> f b) Now there is obvious no map. So I guess it must either be added or the Monads.hs from Haskore have to be patched. Regards Friedrich
