(Also see update in my post above.)

Sure, that's the sort of way I would usually code it myself but you then have to (potentially) explain how that single line works.

The only thing that might have to be explained is that matching in a list context returns a list of the captured subexpressions.

The fragment is idiomatic Perl, so somebody maintaining Perl code should at least be able to read it. I wouldn't think twice about writing it like this.

    I agree it is idiomatic Perl which is why I tend to avoid it in answers to Monks who have yet to grasp the basics of scalar and array context. *Your code is good code* and I personally prefer one line that gets the job done to half a page. I tend towards trying to tailor answers to what I percieve the level of the poster is so I don't have to bother explaining idioms in detail. That is unless I am in a hurry or a smartass mood when I will post brief stuff like Re: Re: Re: Looking Through Arrays?

    cheers
