Not to mention in AltiVec terms, 

	vector char foo
	vector int bar

foo is a vector of 16 characters, and bar is a vector of 4 ints.
So we've changed sizes as well.

I think it makes sense to be able to cast the vectors (which 
valarray would _not_ allow, incidentally), but I do not think
it makes sense to allow assignment without casting.
