It’s the time of year for Advent Calendars and it looks like the Perl community isn’t disappointing this year.
[Perl Advent Calendar](http://perladvent.pm.org/2009/)
> The first day talks about using Package::Alias to alias Mouse to Moose.
[RJBS Advent Calendar](http://advent.rjbs.manxome.org/)
> Ricardo Signes’ calendar to showcase things he has been working on. His first entry is about Sub::Exporter which looks very powerful.
[Catalyst Advent Calendar](http://www.catalystframework.org/calendar/2009)
[Perl 6 Advent Calendar](http://perl6advent.wordpress.com/)
> This one starts off with setting up Rakudo, so it requires very little prior knowledge.
> Tips for system administrators
All of these have RSS feeds, so they’ll be easy to follow. Have fun!
