I think it would be helpful if TestRig offered two additional options that would print for lexer grammars the current lexer mode and the contents of the mode stack.

Actually, it would be helpful when the lexer produces an error. Knowing the current mode and the contents of the stack would help debugging the lexer.

The solution is to override notifyListeners and peek the mode stack for the current mode.
