[Haskell-beginners] A few really short beginners questions

[Klaus Gy]

Yea, Hugs tells me:

ERROR (filepath):3 - Syntax error in instance head (constructor expected)

But since I'm trying to understand Haskell and have nothing particular
in mind with this program, I'm not stressed finding a solution for
this. I'm happy if the code is principally correct.
