That will work in the special case of lists, but there are all sorts of other things you might want to map across.

It is, I agree, not appropriate everywhere, but point-free code can in the right place be much more readable. Maps are a good example. Compare:

    map (f . g . h) xs

to

    map (\x -> f $ g $ h x) xs

Not quite a fair comparison

How about?

[ f (g (h x))  |  x <- xs ]
