If you'd like something that works on JRuby as well, parsetree is 
probably a good choice; there's a clone of parsetree in development for 
JRuby.

However you should keep in mind that basing logic in your application 
directly on the structure of the AST is unlikely to be portable forever. 
The AST is bound to change.
