Thanks, Marpa looks nice. I couldn't get the sample program to run, though:

Can't locate object method "parse" via package "Marpa::R2::Scanless::G" at b.pl line 24.

I guess the other disadvantage is that I would then have to design and implement my own language using Marpa. This could be simple for very simple arithmetic operations, but inevitably I can imagine then having to extend it. Probably better to start with someone else's good design and implementation.
