Indeed, that was one of the most popular choices when I first brought
this topic up. I contributed mips vector support in August 2004, and in
the multiple threads that patch spawne
That said, I'm not happy with a builtin function. I think that we
should make every effort to make
union { TYPE a[COUNT]; VECTOR v; } u;
u.v = v;
x = u.a[0];
use vec_extract, because in the absence of operator[] that is the
natural way for people to extract an element from a vector.
