Ah, thanks. It might be a good idea to add a link in the future, I totally
missed that there was an rpn page.

On the low side, no binary AND/XOR operators :(

I suppose I can emulate them somewhat with something like
x & 64 is equivalent to x 64 / floor 2 modulo
so I'm not dead in the water, but it's a bit disappointing.
