Yes. But it doesn't work in v3 because of the different way that
token generation is handled (ANTLR v2 always copied the token
text; to improve performance v3 doesn't).
There isn't really any particular reason why the functionality
couldn't be re-implemented in v3 (and it'd be useful in quite a
few cases), but that's still sitting on the wishlist.
