[Haskell-cafe] Exercise in point free-style

Hello, I was just doing Exercise 7.1 of Hal Daumé's very good "Yet Another Haskell Tutorial". It consists of 5 short functions which are to be converted into point-free style (if possible). It's insightful and after some thinking I've been able to come up with solutions that make me understand things better. But I'm having problems with one of the functions: func3 f l = l ++ map f l 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? Thanks, Julien
