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.
