The standard operation of the tool will be to generate listener interfaces and blank implementations so that users can keep actions outside of the grammar, leaving them multi-targetable. By turning on a flag at runtime, the parser will build this internal parse tree. A standard walker will then walk that tree and trigger events in the listener. If all you care about is what happens up on some variable declaration, you simply implement that listener method.
