[Haskell-cafe] Library function for map+append

[Dusan Kolar]

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
