Yes, I was asking about Perl features in emacs' regexps.

Like all the operators with "?" prefixes.

Actually, I'm surprised someone hasn't already (years ago, even)
given some of that stuff a try.

Ilya, for instance -- he's such a whiz at implementing those
fancy regexp features for perl, making (I think) use-anywyere 
libraries of them, and so on.

---

Just in passing, that Friedl book, "Mastering Regular Expressions",
is really worth having in the library.  (So you can dream of
what you could do so easily were they in emacs too!)


Thanks for all the comments!


David
