What you have to do is , lets say you have a grammar


     ( statement )+

statement: ....;


Now you add an orphan rule

     statement EOF;

now you can use the orphan rule ( once you attach the string stream to
your parser/lexer )

to return to you an AST.

You can even create a separate parser, as long as you create a context
outside of the original parser, so that you can keep track of your
and pass it to the constructor of the parser.

If this is too cryptic, I can expand on it next week. Right now I don't
have the time....
