Just a random thought, What would be the effect of lifting the monomorphism restriction under the condition that assignments which would normally be subject to the restriction must be memoized on the class constraint parameter by the implementation? it seems that this would solve the problems which inspired the monomorphism restriction since the value can be shared among all instantiations when the type is the same. I am posting this to haskell-cafe because it might just be half-baked.
