clean semantic AST?
Pegged can help you with that filtering part, at least to some extent.
Remember you can use : and ; prefix operators in the grammar spec, and
Pegged will drop the needless nodes for you.
Or do the reverse, use ^ prefix operator (or write a new rule) to make a
node out of Pegged builtins.
