Hello all,

During a small project I'm trying to develop a small application. It becomes quite often that I need a function mapapp:

mapapp _ [] ap = ap
mapapp f (a:as) ap = f a : map f as ap

I tried hoogle to find such a function with no success. Is there any function/functions built-in "standard" libraries that could easily satisfy the functionality with the same or even better (?) efficiency?

Of course, (map f list) ++ append
 would do the same as

mapapp f list append

 but with less efficiency. Or am I wrong?

 Thanks

   Dusan
