This isn't a "regular expression", it's a "regexp" =] - see comments on HN:
This script uses backreferences which give regexp's more "computing power" than regular expressions actually have, but remove the guaranteed runtime of an O(n) regular expression. For more, read the excellent article at http://swtch.com/~rsc/regexp/regexp1.html
You can actually prove that "regular expressions" don't have the computing power to enumerate the prime numbers. For more, read the wiki article, http://en.wikipedia.org/wiki/Pumping_lemma_for_regular_languages
On an unrelated note, I've been a longtime fan of your NodeJS articles, and look forward to more of your writing. =]
I have studied computer science intensively and you're right that this regular expression isn't a real regular expression as in automata theory.
I'm publishing the next nodejs post in a few days!
