[antlr-interest] 3.0 C++ wishlist

[Paul Johnson]

Can we please have virtual getParent and addSibling routines in 3.0? 
This will save lots of typecasting:

virtual RefAST getParent() const;
virtual void addSibling(RefAST);

'setParent' might be nice as well, but may be unnecessary, since you can 
implement it by over-riding 'addChild'/etc.

Some AST iterator functionality would be nice, but may take some 
thinking about.

are there any preprocessor macros that'll let us know what ANTLR version 
we've got?
