I have to strongly agree. I have already written things like
fmap (fmap (fmap (fmap f)))
and find it hard to find out later, which fmap refers to Maybe, which one to List, and which one to Map. That is, I prefer 'map' even if there is an 'fmap'.
But this problem comes up /anywhere/ you are composing polymorphic functions. Just renaming functions in the case of `fmap` just solves that particular problem, but doesn't solve the problem in the general case. I think this is a problem that is truly solved best by editor tools.
I'd prefer to be able to read such code without the help of an editor. E.g. map (Map.map (Maybe.map (map f))) makes everything obvious without any tool.
