Recursive regexps?

It seems there are a *couple* of (experimental) PCRE features that
allow recursive matching:

  [T]here is some experimental support for recursive patterns using
  the non-Perl items (?R), (?number) and (?P>name). Also, the PCRE
  "callout" feature allows an external function to be called during
  pattern matching.

All of these seem pretty useful/neat :-}
