Persumably you mean "quot" and "rem", since Enum is a superclass of Integral, not Num. toInteger must have been even worse, right?
- what's the deal with fmap and map?
I think this one is historical: map already existed before Haskell was powerful enough to type fmap, and the decision was not to affect existing programs too much. Presumably Haskell 2 will have them merged. Best, Dylan Thurston
