[Haskell-cafe] Exercise in point free-style

[Julien Oster]

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
