Awesome. If I ever have a use for it, and I'm certain I will, I now know precisely where I'll go. Anyone know how much slower this thing runs?
edit: nice. I never knew about those regex inconsistencies on browsers... I'll have to keep an eye out for these now.
Sorry, but the only thing more painful to read and edit than pure regular expression syntax is string-escaped regular expression syntax. I still cringe when I remember writing this in C and Java.
