Although it should be pointed out that these days Piers does a lot more Ruby than he does Perl...

update: having reached the end of the article, I read that Piers is beginning to work with Perl again. If you've ever talked with him at a conference about Perl, you'll understand why I say: Yay!

From his bio: "Piers Cawley is a veteran Perl programmer with 10 years service who has spent the last couple of years in a lucrative dalliance with Ruby, but who is returning to the Perl fold for personal work. Between 2002 and 2005, he wrote regular summaries of activities in Perl 6 development for perl.com."
