I am a -1 on both proposals, i.e., on having a special map for the "apply to a fixed argument" case.

Also, since the variable input of this combinator seems to be on the
functor side I suggest to inverse the arguments order order, i.e.:

     mapf :: a -> f (a -> b) -> f b

This way it'll target composition. And since it's a combinator over
functions it's a pretty important thing. E.g.:
     mapf 2 . map (*) $ [1..10]

I'd simply write

  map (2 *) [1..10]
