Wait, does that mean J and K don't work if you're storing temporary
values on the rstack, as is common in Forth?  Yucch, that sort of
defeats their purpose, I would have thought.

I find myself wishing Forth had a bunch of extra stacks for various
purposes.  With enough of them, they could be just one level deep, and
then they could be called "registers".
