I had hoped that the code below (GHC 6.10+) would work, but it just sends GHC into a loop when you actually try to typecheck (1,1). I don't know if that's a bug in GHC or a misunderstanding on my part of how the typechecking should work.
A loop without turning on a flag to allow it must be a bug.
Sorry, I didn't mean to say "typecheck (1,1)". I meant to say "evaluate (1,1)*(1,1)" - I had a suspicion that some kind of infinite polymorphic recursion through the Num instance is happening and accidentally turned that thought into a completely different statement.
