Question: I didn't realize until recently that Perl 5.10 had significant new features and I was wondering if anyone could give me some good resources for learning about those. I searched for them on Google and all I found was some slides and a quick overview. Some of the features (to me at least) would be nice if they had more explanation.

Any links would be appreciated.

Answer: 
There's been a string of articles in [Perl Tips](http://perltraining.com.au/tips/) about Perl 5.10:

* [Regular Expressions in Perl 5.10](http://perltraining.com.au/tips/2008-02-08.html)
* [Perl 5.10: Defined-or and state](http://perltraining.com.au/tips/2008-03-03.html)
* [Switch (given and when)](http://perltraining.com.au/tips/2008-03-12.html)
* [Perl 5.10 and Hash::Util::FieldHash](http://perltraining.com.au/tips/2008-03-25.html)
* [Smart-match in Perl 5.10](http://perltraining.com.au/tips/2008-04-18.html)

There are also my *What's new in Perl 5.10* slides on [Perl Training Australia's presentations page](http://perltraining.com.au/tips/2008-04-18.html), but since they were written before 5.10 was released, some things may have changed slightly. I believe that rjbs' [Perl 5.10 for people who aren't totally insane](http://www.slideshare.net/rjbs/perl-510-for-people-who-arent-totally-insane/) now covers everything my slides used to.

All the best,
