How can I get up to speed about Perl's latest object-oriented capabilities? [closed]

Question

I have not done Perl for about 8 years and now I'm going into project that's heavily utilizing object-oriented Perl so I need to resharpen my Perl skills and do it quickly. During these past years I mainly did all sorts of Java development and some PHP. I'm very good at OO and I'm not a novice programmer by any remote extent.

So here comes the question: what are the best resources/sites/practices/ways/books you guys can recommend to pick up on my rusty Perl skills and learn Perl "the new way"? Your suggestions will be much appreciated.

P.S. I did researched some previous answers. I want to emphasize that I'm not looking for novice book/resource (syntax, core principals, etc) but specifically ones that cover OOP capabilities that weren't there when I was programming in Perl (or I may overlooked it at that time)

P.P.S. Thanks to everyone for their suggestions and tips. After some consideration I went with @MBO answer since it's first mentioning Moose which I really like so far.

Answer 1

I don't write Perl code at this time (currently I work in other languages), but I read from time to time this site: http://www.modernperlbooks.com/mt/. Also check Moose for new way of defining objects in Perl
