[antlr-interest] How to do complex Tree Pattern Matching

[Terence Parr]

yeah, I realized that I had opened up a huge issue without thinking it  
through. I'd like to have something like inContext but the more I  
added to it, the more I realized that the simplest thing to do would  
be to give the programmer basic tools like hasAncestor and let them  
add whatever logic they need.
