[lojban] Re: Computer grammar question: non-left recursive RPN?

[Jo l'apache <jolapache@free.fr>]

rp-expression = rp-operand rp-operand operator
rp-operand = operand / rp-expression

here is the version without left-recursion

rp-expression = rep-operand rp-operand operator
rp-operand    = rp-operand' rp-operand
rp-operand'   = () | rp-operand operator

I think this version is correct, but i'm too busy to check it now.
