The London Perl Mongers, together with BBC Backstage have organised a one-day Perl Teach-In day to be held at the BBC Broadcast Centre on Saturday 2nd June.
You can get more details (and can sign up) at http://london.pm.org/teach-in/.
I'll be running the training, so I'll be happy to answer any questions, but note that this is _not_ a course for beginners. You'll need to already understand things like references and writing modules in order for the course to be worthwhile.
Update: Registration is now closed. We sold out in 48 hours. I guess it's true what they say - Perl really is dead :-)
