Hello, world!

This is Simon Cozens, managing editor of www.perl.com, here to
bring you the week's news and developments both in the Perl world
and on our own site.

* Perl at large.

Well, the world has been struck by Larry's Apocalypse and Damian's
Exegesis on Perl 6 operators, and I'm still getting lots and lots
of questions about what it all means. Damian's been frantically
trying to help out on Slashdot, Perlmonks, use.perl.org and other
communities to explain what we actually mean and dispel some of
the FUD that's arisen about the latest changes to the languages.
Maybe you want to catch up with that discussion:

    http://slashdot.org/article.pl?sid=01/10/03/2121203&mode=thread
    http://use.perl.org/articles/01/10/03/2327208.shtml

    http://use.perl.org/articles/01/10/05/2115241.shtml

Mac users will be delighted to know that the first beta version of
5.6.1 is available; and yes, you can build it with free tools. Go
out and give it hell...

Finally, there's plenty going on behind the scenes: Damian's working
away on some great modules - as well as updates to Filter::Simple,
Class::Multimethods, and a whole new set of Attributes:: packages
to get around the limitations of Perl's attributes. We look forward
to them with eager anticipation!

* What's new on perl.com

The perl5-porters summary is back! Ahbijit Menon-Sen has done a
grand job bringing you the summary, including all the work on
testing from chromatic, Why Artur Thinks Attributes Are Broken,
and many other exciting and interesting things...

A few weeks ago, we looked at my Mail::Audit module for filtering
email. I'd be the first to admit that, while this is great for
filtering personal email accounts, it's not the thing you want to
use when you're filtering incoming mail for an entire site. For
that sort of thing, you need Perl support built into the incoming
mail daemon. That's precisely what ActiveState's PerlMx product
provides, and it's exactly what this week's feature article covers.
Mike DeGraw-Bertsch brings you the first in a series on PerlMx,
explaining how to develop your own spam trapping mail filter at
the MTA level.
