Point-free style and using $

Question

How does one combine using $ and point-free style?

A clear example is the following utility function:

times :: Int -> [a] -> [a]
t         


        

Answer 1

You can easily write an almost point-free version with

times n  =  concat . replicate n

A fully point-free version can be achieved with explicit curry and uncurry:

times  =  curry $ concat . uncurry replicate
