Hi,

Do you want to apply tail and then head on the list?
If so, you can write:

head $ tail [1, 2, 3]

Besides the dollar opeartor there is a dot (.) operator. You can read more here:

Regards,
Daniel

Hello Carl, simply

    λ> tail [1,2,3]
    [2,3]

will do! Haskell is not a Lisp, no need to wrap expressions
around ().
