As far as I know, there is no standard function doing that, though it is
easily implemented:

mapApply xs x = map ($ x) xs

or just:

mapApply x = map ($ x)

If you don't mind the parameters being reversed.

The 'mapApply' name is probably terrible, I'm sure other people would
have better suggestions for the naming :-).
