Note Submitter: corey removeme effim removeme com ---- In response to 'Anonymous' below, Perl Compatible Regular Expressions are FAR more powerful than their POSIX counterparts, which is exactly why the latter are being deprecated and removed. There is very little additional work required to use them – it's merely a matter of script kiddies being afraid of them that causes lots of performance issues. They absolutely should be removed. PCRE are here to stay – just look at your favorite text editors and every other popular high-level language – they all support them.
