in thread Regex: matching character which happens exactly once
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.
