What is Python's answer to Perl 6?

Hello,

another Perl/Python question: the subject says it all.

Perl is going to change dramatically to become a more powerful and
easier to (read|write) language.

Is Python taking a similar step (-> Python 3) some time in the near future?

Reinhold

assert("Perl 6" < "Python 2")

Somehow I suspect that assertion will hold for the foreseeable future,
no matter how much the numbers change <wink>

Why do you say this? Did you read the whole Apocalypses? Anyway 15 days ago
freshmeat published this:

Maybe, it's not that easier to read or write.

Why? What do you need to do in python that you can't do right now? Isn't it
read-write friendly enough?

Perl6 is, currently, a 4 year development effort that no one knows when will
be ended (I even read that it will take another 4 years), maybe, if it takes
so much to develop just the first version, it's really too complicated.

The virtual machine underlying the Perl 6 language, Parrot
(www.parrotcode.org) will also support running Python. This will
probably incur performance benefits as well as allowing some interesting
interoperabilit y between Perl 6 and Python-on-Parrot.

Whether Python-on-Parrot will become the official Python: I don't know.

Yes, I read most of the Apocalypses, the Exegeses and the Synopses.

For average programs, it seems that it will. Just think about classes.
One thing the freshmeat article complains about is breaking
compatibility. Well, you can't correct design mistakes by keeping old
syntax around.

A great plus will be the new regular expressions.

That's a point. The whole object system (roles, interfaces, etc.) is far
too complicated and almost no one will need it.

PS: I'm happy with Python, and I'm not going to complain about it. But
as a programmer who uses both languages, I'm just asking because I'm
curious...

I'll believe the performance benefits when I see them. The Parrot people
promised they would be faster by OSCON 2004 or Guido would get to pie
Dan Sugalski in the face. If you don't already know what happened, you
can see a picture here:

I hope it worths the effort :P

Correct, but breaking everything in the language will make Perl6 a
completely new one, just preserving the name. And the community will have to
relearn from scratch to love it. Are you ready to almost trash all the
current perl5 library?

I actually hope python 3.0 is not that far away, since there are some tiny
things that really need to be fixed in python2. Perl and Python, after all,
have a very different philosophy and the featurefulness of perl6 will be
matched with the extreme simplicity and clarity of python (which is also
a feature)

The list of features for Python 3000 is described in PEP 3000,
appropriately enough:

http://www.python.org/peps/pep-3000.html

Most of the suggested changes remove redundancy, such as removing
now-unneeded built-in functions and language features.

Well, if they are any good we'll just port them to Python. "import
re2" and we are all set. Everyone wins.

Overall, there seems to be some kind of minor consensus (to the extent
it means anything in the internet) that perl6 is a disaster that is
taking way too long to happen. Implementing (rather making the design
decisions) py3k seems trivial in comparison.

well, they failed to implement all of the tests but those implemented
actually run faster than CPython.
Anyway they are at 0.1.1 or something like that. There is time to become
faster or to disappear completely, I guess

My area of research is in CAD algorithms, and I'm sensing the need to resort to something more expedient than C++, bash scripting, or sed scripting.
