However, there's something else peculiar here: the bottom of the perl interview page you cite (and link) says: "Check out Perl Monks for discussion of the questions and related Perl interview issues. Check RegExpLib for regular expression samples." RegExpLib appears to be site which provides advertising for regex-related software... but the reference and link to Perl Monks raise (for me) the further question of whether someone is using the Monastery's good name as an implied endorsement of a product?
I should note, tho the pm link is to the Gates, so I suppose the reference and link could have existed prior to the OP's initiating this thread.
