Sorry, I think my sentence:

is not quite correct.  I meant that to define any operator in Haskell you have to
have a type class defined with that operator as member.

What? An operator is just an infix function, taken from the set of symbols. Any function can be an operator (and is, via `func` syntax). No typeclass is required to define a random operator.

What did you really mean to say there?
