Hi Julien,
func3 f l = l ++ map f l
func3 f = ap (++) (map f) func3 = ap (++) . map
Looks pretty clear and simple. However, I can't come up with a solution. Is it even possible to remove one of the variables, f or l? If so, how?
I have no idea how to do this - the solution is to log into #haskell irc and fire off @pl - which automatically converts things to point free form. I'm not sure if its possible to do without the auxiliary ap (which is defined in Monad).
