This is reminiscent of an argument I had with the Mercury Prolog guys regarding "typing" in logic programming. My point boils down to this:
Any predicate can be considered a constraint. Types are constraints. While it may be reasonable to have syntactic sugars for type declarations that, at compile time, are transformed into predicates, it is unreasonable to lard a completely different kind of semantics on top of an already adequate semantic such as first order logic.
