Perl6 would make you love Perl for being a better tool again ^_^ It has all the features python has over Perl5, except for the syntactical whitespace strictness. And that's totally subjective.

Python has a killer feature by comparison, actually. It has a living, widely used implementation.

    He was comparing with Perl6, I think.

    I think he means that Perl 6 doesn't have a living, widely used implementation. The point is that since Perl 6 is relatively less mature, it would be more valid to compare Python 2.* to Perl 5, and Python 3k to Perl 6.

      But the difference between Perl 5 and Perl 6 is much more significant than Python 2 and Python 3k.

  Which one, Python 2.x, or Python 3000?

  And several faster but less-complete implementations; PyPy, Unladen Swallow, Psyco, etc. Wow, just like Perl 6.

  So does Perl5. And with a little help from CPAN, the same feature set. In fact, I'd argue that the Moose metaprotocol is substantially more powerful than the one available in python - though if there's a python library that provides the same sort of level of capabilities, I'd love to hear about it - maybe we can steal some good ideas from them :)

    Moose is far more powerful than Python's model. Python seems to think it knows what's best for the programmer. Perl tends to think the programmer knows what's best for it. AFAIK there are no packages for Python yet that implement roles, multi-methods, and the like... yet. But Perl is already ahead of the curve in this arena. (I'm one of the rare few apparently who can speak Python and Perl fluently. I actually like both languages for entirely different reasons.)

Is Perl6 backward compatible? Because what I really hate about perl is how you end up changing how it works by assigning to a variable named something like $@_, or dozens of similarly non-obviously named variables. In the mean time, I guess I will just stick to ruby.

Forgive my cynicism but when exactly is Perl 6 coming out? Python 3 is already out and it was a concerted effort to clean the things that began to pollute the language. Perl 6 is supposedly doing the same thing...but the need to throw everything out makes its delivery rather questionable...I think our sun may become a red giant before Perl 6 shows up.

  I'm a Perl5 programmer so I don't really care (though the Rakudo implementation of Perl6 should be at least worth a test drive sometime next year from what I hear from the other camp). v12 of the runtime for -my- language of choice should be out in the next couple of months, complete with pluggable keyword support blessed in core and a whole bunch of other goodies. And Perl5 is being cleaned up over time - strict and warnings going on by default if you ask for a new enough version of the VM, old and weird misfeatures going through deprecation cycles, etc. Perl5 and Perl6 are two different languages from the same family, not a "next version" and "previous version" like python is - the confusing naming is a historical accident from before Larry turned Perl5 over to its community and we got the chance to pick up development again.

    Which does not mean it's complete in any way - they simply release what they've got at that point: http://rakudo.org/status http://rakudo.org/status "Common things that are known to have problems or not work in Rakudo (As of 2009-02-28.)" list contains "variables in regexes". It doesn't really matter how often they release in that case... That's "as of february this year" and still open in november.

This thread was about Perl5. Perl6 is a separate language in the same family and not relevant to this conversation. Of course, Perl5 now has most of the interesting features of Perl6 anyway, given things like MooseX::Declare - to the point where we're currently helping the Perl6 community steal things back from Perl5 based on our experience using the additional capabilities in production (i.e. "thanks Perl6 for letting us steal stuff, here's how it works out in the real world" - the Open Source way :)
