+Regexp::Grammars version 1.010
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.

+The Perl 5 regex engine is not reentrant. So any attempt to perform
+a regex match inside a C<(?{ ... })> or C<(??{ ... })> will almost
+certainly lead to either weird data corruption or a segfault.
+
+The same calamities can also occur in any constructor called by
+C<< <objrule:> >>. If the constructor invokes another regex in any
+way, it will most likely fail catastrophically. In particular, this
+means that Moose constructors will frequently crash and burn within
+a Regex::Grammars grammar (for example, if the Moose-based class
+declares an attribute type constraint such as 'Int', which Moose
+checks using a regex).

The additional regex constructs this module provides are implemented by
rewriting regular expressions. This is a (safer) form of source
filtering, but still subject to all the same limitations and
