>I pointed out that the type system _may already_ not terminate I agree, I have made it not terminate myself with undecidable-instances, I also think prolog style backtacking would be a good idea... I think I said that you either want full backtracking or you want to leave it how it is (with dependancies ignored) - I have yet to be convinced that any partial solution would have the elegance of full backtracking, yet would complicate the implementation and syntax.
