Library function to compose a function with itself n times

Question

Is there a library function available in Haskell to compose a function with itself n times?

For example I have this function:

func :: a ->

A variation on trinithis' answer using the newtype package, just for fun:

(\n f -> under Endo (mconcat . replicate n) f)

Or point-free:

under Endo . (mconcat .) . replicate
