I think map would be the right name. IMO, what would be really nice
would be to rename "fmap" to "map" (and then fmap would become a
deprecated synonym for map), etc., and get rid of many of the special
cases for lists in the Prelude. The only backward compatibility
problem that has been brought up is monomorphism restriction stuff,
though.
