Summary of Paul's Perl talk
For the benefit of Debian users, here's a quick summary of Paul Fenwick's talk about cool stuff in recent Perl versions.
apt-get install libmoose-perl
apt-get install libpar-packer-perl
apt-get install libdevel-nytprof-perl
apt-get install libautodie-perl
apt-get install libperl-critic-perl
Now I have to integrate all that into my writing of Perl programs, which doesn't really happen frequently enough for such changes to become easily ingrained... Great fun, and it's tempting to install Windows just so I could run some of that stuff, but perhaps Paul hasn't realised that you can run Minesweeper under Wine?
Moose and Critic
I've recently come back to perl after many years and have been pleasantly surprised by some of the things you mentioned that were developed since I last used the language. Moose is very cool, but you should also check out Mouse (libmouse-perl) which is a faster subset of Moose that's much more basic. If you find that you need something more complex than what Mouse offers you, you should be able to s/Mouse/Moose/ and be able to start using what Moose offers.
Additionally, Critic is absolutely wonderful for someone like me, who's not steeped in many many years of perl's quirks. It's a wonderfully flexible tool that catches a ton of very simple things, and provides some amount of standardization across codebases. It codifies what it can from Conway's "Perl Best Practices" so you don't have to memorize the book. I really can't recommend the tool highly enough.
Thank you very much for pointing out the others, the only one I knew of was NYTProf, but I haven't looked at it. libpar looks very cool, I can't wait to have a look at it.
