OO interface for the gnu regex engine
This is a port of the glibc gnu regex engine into perl. There are few reasons you would need this. The few I can think of include
0 You wish to use untrusted user expressions in such a way as to be able to catch errors. Example eval alarm 2; m/10241024/ is an instant uncatchable segmentation fault. GNU’s regexps will still fail, but in a timeout way rather than an instant segfault way.
1 You wish to have POSIX compliance on … something … Perl’s regexps are slightly different – arguably better, but different.
