That's an interesting idea.  OK, so possibly I was wrong -- I hadn't considered
that stack-push/stack-pop operations might introduce overhead comparable
to the order-of-magnitude speed difference between registers and main memory
in hardware.  I'm still skeptical, but my mind is open.

You know why there's a Second Amendment?  In case the government fails to
follow the first one.
