Before I go, one last point; I'm not sure how the declaration of operators can be *completely* orthogonal to type declaration; after all, there's not much point in declaring a type if you can't actually do anything with it. I understand that not all operators may be defined when the data type is first introduced, but at least some operators (equivalence definitely) will have to be there pretty much from the get-go.
