I'm not entirely clear exactly what you want to do, but I
suspect it's entirely possible. ;-)

Are you aware that you can define other methods in the 
Parse::RecDescent namespace, and they immediately become
methods of any parser object.

If I'm not on the right track here, you'll need to send
me a (short!) example of what you want to achieve, and
as soon as I understand it, I'll tell you how.
