That's a "left recursive" grammar, which gives Recursive Descent compilers (of which P::RD is one) a hissy fit.

I believe that the P::RD examples include a simple parser that actually works. {grin}

    DOH! I was in such a rush that I didn't check that the grammer wasn't left recursive. Hmm... wouldn't swapping the order of the nonterminals in expression and term make it 'right recursive' and solve the problem?
