José Castro took a break from organising the conference and presented Perl Black Magic - once and for all - Obfuscation, Golfing and Secret Operators. This talk is all about obfuscation: No spaces, use newlines or use indentation wrongly. It's all about confusing the reader, so if you happen to use deep Perl knowledge and uncommon options to make the reader think something else is happening, you have won! Then he went on to golfing and secret operators. What does this do?
[$x => $y]->[$y <= $x]Not a terribly practical talk, but very fun.
