bvec and/or/xor operators?

Can we have and/or/xor operators/relational functions working on boolean vectors? Currently we have to cast them around to get the functionality (on specs-conforming ATI/AMD).
I don’t know what was behind the decision to not support the usual operators on boolean vectors, but it would be nice if at least the extra relational functions were complete.

I follow this request! It would be nice to have this feature.
