Perl's Extreme Makeover
PurdueGraphicsMan writes "There's an article over at Yahoo! about the upcoming version of Perl (version 6) and some of the new features (RFC list). From the article: "Although Perl 5's expressions are the most sophisticated available and aspired to by other programming languages, "no one pretends for a moment that they're anything but hideously ugly," said Damian Conway, a core Perl developer and associate professor at Monash University in Australia.""
If you want the real scoop on the on-going planning of Perl 6, you might want to check out Larry Wall's Apocalypse articles: 1, 2, 3, 4, 5, 6. On the down side, they are dense. Very dense. For that reason, I actually recommend Daimon Conway's Exegesis articles: 2, 3, 4, 5, 6. They provide alot more context on what the changes actually mean to you and why they're good.

I cannot claim to intimately know Perl 5, but I started learning it a few years back. I belong to the camp of Perl programmers (and I know there are a few of these) who are adopting a "wait and see" attitude to Perl 6.
If you're interested in learning Perl now, you should probably go for the cookbook approach, ie: get a copy of OReilly's Perl cookbook and just try applying the solution to your problem. Then, trying tweaking and figuring out how it works.
As for learning Perl 5, I'd probably point out that there are still some places that run 5.005_03 (certainly Solaris used to ship with that version by default), and that version is at LEAST 5-6 years old :) There are even some places I've heard of that run Perl 4 :) So, I think there is plenty of time to have your investment in learning Perl pay off before people start switching to Perl 6 en masse.
Personally, I found that perl was kind of odd and not fantastic until I learned perl with regexes [via O'Reilly's Mastering Regular Expressions, highly recommended]. Then alot of the little nuances made alot more sense. Alot of the examples in that book were things perl does easily in a few lines, but would cause most programmers to gouge their eyes out if they needed to do it in C.
You might be interested in Ponie, then. Ponie is the project to create a Perl5 interpreter for Parrot. It should let you get much of the speed benefit of the new virtual machine without having to learn the new Perl6 syntax. Of course you may still want to learn the new syntax, since it will add many powerful new features, but Ponie will ensure that Perl5- and all of the work you've put into your Perl5 scripts- won't be completely abandoned just because Perl6 has come out.
There's no point in questioning authority if you aren't going to listen to the answers.
A few points to ponder ..
You've all heard the "you can write unreadable code in any programming language" argument, so I'll spare you the repetition.. (No, wait.. I didn't, did I? ) *grin*
But also bear in mind that Perl is the first language that I know of that used the foreach construct in the same form as the more sought after languages.. Java has iterators and enumerators, but they introduced a foreach because it is darn easy to understand.
Perl innovated in regular expressions. Even Jeffery Friedl's Mastering Regex (sic) says that other languages aspire to be called "Perl 5 compatible" when they don't necessarily support all the features of Perl 5.6". Love it or hate it, regular expressions are like the microwave in your kitchen. Once you get used to it, it's darn hard to manage without :)
I am not going to go into Perl 6 the moment it is released. But I guess that's ok, because I didn't adopt 5.8 the day it was released either. I just think that Larry Wall has made enough good calls in the language so far, to be worth trusting him for another version. Even one that promises to break some of the idioms that I am accustomed to in it's present incarnation. Hey, I didn't like Perl 5 when I first saw it either, but I notice the difference in my productivity when I got the hang of things.
