[antlr-interest] How to force a TreeWalker to match exactly?

In my opinion I need two things:
      * Complete tree parsers that check for everything (translation)
      * Matchers that search the tree for certain patterns
        (optimisation)
Both are not exactly what ANTLR 2 is providing at the moment.

IMHO it would be very nice if this was an option in tree grammars in v3.
