I wouldn't wait for people to argue about the right AST either. Use
the one Greg and Bill came up with for p2c. It's in Tools/compiler in
the Python distribution. It's much simpler than the parse tree
produced by the parser module. And, as far as I know, no one is
advocating a different AST.
It doesn't have a query language, but neither does tokenize.py <wink>.
