I suspect we may be in need of a target hook :-) for VECTOR_TYPE comparison, since it appears that SPE and AltiVec (not to mention MMX/SSE) may require different semantics in this regard. A one-size-fits-all approach for vectors may not be feasible.

Hmmm... this seems very much overkill...

The C++ example I posted is just a case in which we see the difference between being the same type vs. having a default conversion. Opaque types are the same type as other opaque types, but have a default conversion from and to all other vector types.
