Summary: Add grammatical parsing features to Perl 5.10 regexes

Description:
This module adds a small number of new regex constructs that can be used
within Perl 5.10 patterns to implement complete recursive-descent parsing.

Perl 5.10 already supports recursive=descent _matching_, via the new
'(?<name>...)' and '(?&name)' constructs. For example, here is a simple
matcher for a subset of the LaTeX markup language:

$matcher = qr{
(?&File)
