What's New in Perl
Ricardo Signes will be giving a talk at YAPC::NA 2012 that he describes as:
There are almost twenty thousand lines of documentation describing what has changed since perl 5.8. Those docs are where you can find out that the // operator is awesome, or that the “r” flag on substitution is going to save you typing and bugs, or that you can stop worrying so much about your exception handling. Unfortunately, they also contain a lot of talk about things like GSVS_mg_SLOPPY or engine derecursivisation or what happens now if you try to reset a glob reference during global destruction. With most common Unix distributions now shipping Perl 5.12, and more and more workplaces moving off 5.8, many programmers are faced with reading these documents. Instead, you can come listen to the forty minute summary.
