I saw Larry Wall at one of the conferences. He talked a about Perl 6 how it was progressing and such (it was before it was renamed) and year, expressiveness what stuck out. It certainly has lots of nice features, too. But at least for me, I realized with Perl 5 I wasn't smart enough for it. I would be lured by the clever short expressions and then sometimes later look back and had no idea what I wrote.
Larry is a great person, btw. During lunch at the conference sat at his table and he was very approachable and warm. I don't remember what we talked about exactly just that it I liked how down to earth and nice he was.
