The hot topic of proper E-Mail validation!

I would like to see more about the limitations of regular expressions. Particularly when applied to computability theory. I.e. what can regular expressions mathematically do easily and where do they fall apart? What other data recognition and decision processing methodologies are there that compete with Perl style regular expressions? What methodologies improve on perl regular expressions, if any?

Perhaps these are questions for a later post. I'll hound you until I get some discussion about this or until I get some time to write up a discussion on the maths & technical side of regular expressions myself!

In any case, nice primer ben. Looking forward to part 2!
