One way to make the job easier is to have P::RD bless each node in your parse tree (look up "Autotrees" in the module documentation or take a look at demo_LaTeXish.pl and demo_eval.pl that come with the module). Then you create methods in each of the node classes, and let them work out the tree traversal themselves. > Anyway, this is a nice final design, though.
