I'll definitely plan to do that, as soon as the license questions
are solved and it's clear from which existing skeleton I'll
derive the pull-skeleton.

But the basic idea is simple.  For lalr1.cc I defined in the header
a class ConstIterator inside of class Parser, and the parse()
function is just the operator++() of ConstIterator.

And after reduce, instead of "goto yynewstate" I just do a return.
Of course there are some more details to it, but that's the basic
idea.
