He came in June, or maybe late May, signed books, and talked/answered questions at my Advanced Perl class. He's friends with our teacher.

Was a real treat. A real nice humble guy. I posted in r/perl at the time. He's active in #perl6 on freenode, I believe.

It's a shame that he's had health issues.

He was there at YAPC::EU 2013 in Kiev.
