It’s been a long-time topic of discussion in the Python camp: Python 3.0, also known colloquially in the Python community as “Python 3000” or “Py3k”, and today it got a little more real. The first alpha release of Python 3000 is now available for download, just in time for those of you who want to test-pilot it over the Labor day weekend.
(If you’re waiting to get a final version before downloading, you’ve got a fair bit of time. The current best estimate for the release date of that version is August 2008.)
Unlike Perl 6, which is a radical reworking of the language, where every feature is subject to change, the idea behind Python 3000 was correct a specific set of design mistakes. These corrections are large enough that they will break programs written in existing versions of Python, but which provide gains that are enough to make the trade-offs worthwhile.
