[issue694374] Recursive regular expressions

[Matthew Barnett]

Matthew Barnett <python at mrabarnett.plus.com> added the comment:

Perl (?number) for calling numbered groups and (?&name) for named groups
 (Perl also supports (?P>name)). (?R) is equivalent to (?0).

It's interesting that the documentation for both Perl and PCRE say that
they support (?P>name) because that's what Python uses!
