[Haskell-cafe] Repeated function application

Hello I was surprised to be unable to find anything like this in the standard libraries: times :: (a -> a) -> Int -> (a -> a) times f 0 = id times f n = f . (times f (n-1)) Am I missing something more general which would allow me to repeatedly apply a function to an input? Or is this not useful? I thought this looked a bit like a fold, so I tried expressing it like this: times f n x = foldl (flip ($)) x (replicate n f) ... which horrifies me, but I can't help feeling that there must be a way to get rid of the explicit recursion. How would you implement times? Ben
