Yes. Like LanX, you're getting bogged down in implementation.
What do you want it to do with that syntax? How would you redefine Perl regexes to do this? I think another symbol for backref would help. (I don't know what we'd use, but that's a different problem.) Then use the same thing for forward references. And for fun, we'll call those ferkcabs. -QM
