Otherwise, you introduce asymmetric behavior into the assembler... i.e.,
higher probability of coding errors IMO.  That's more confusing than an
oxymoron.  ;)

It' not likely I'd ever need it, but if I did it's likely I would expect
'mov ax, ds' in BITS32 to execute exactly like BITS16 - leaving upper bits
alone...  As for the cpu dependent version, it's possible someone could be
using that "defect" in a cpu detection routine.

I guess I believe in "Do no harm." when it comes to assemblers.
