In paris the keyboards seems better.

I think I've ironed out all the issues in my handwriten code, but I
don't have time to type it up. The only thing I'm not sure about is
whether the compiler will produce better code on a switch statement or
a bunch of ifs -- and whether the binary will become smaller if I omit
the 'else's in the 'else if's.

Sorry to keep everybody waiting. The parser supports order of
operations, parens, and all the operators from ash. I even ironed out
some situations that were special cases -- Unary minus vs. binary
minus, making sure that 5/2*2 evals to 4 and not 1( basically
supporting equivilent procedences for operators), and allowing
multiple unary operators in a row. The code looks quite promising and
I can't wait to share it.
