I've been thinking back over the presentations that I saw at YAPC this year. Here are two techincal insights that will stay with me:
1. Inline::C isn't really a replacement for XS. It's a replacement for h2xs.
2. Two actual uses for closures: memoize (uses closures internally) and strong object encapsulation.
And my personal YAPC Awards:
1. Best argument for why we need Perl 6: Adam Turoff -- Perl 6 has re-energized the Perl community.
2. Rudest YAPC attendee: perhaps I shall refrain from naming names, but STOP INTERUPTING PEOPLE just because they're criticizing the usability of CPAN.
3. Coolest hair: easy one. Michael Schwern.
4. Best presenter: hmmm. Tie between Dominus (Secrets of the Wizards) and Kevin Lenzo's (the auction).
5. Most entertaining session: Lightning talks
6. Most eloquent explanation of the power of Perl 6: Allison Randal, if Dr. Seuss were a Perl 6 hacker
