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.

Thank You very much for the fast reply! I think I expressed myself badly in the first question. What does not work is the following:
class Test a
instance Num a => Test a
What do you mean "doesn't work"? Do you get an error? Or it doesn't have the behavior you expect? This ought to work fine.
