Python Language Moratorium

[Gasto]

A new PEP surprised me. The Python Language Moratorium.

Basically Python's new syntax changes arising since the idea of
Python 3000, have come to a halt for at least 2 years. This will help
alternative python implementations (IronPython, Jython, PyPy, Unladen
Swallow) keep up with the changes.

So we'll have Python 3.1.x for a long time. I think it is good. But
some believe it's a halt to progress.

I've been following that on Python-dev (I just lurk there). Python
3.2 and 2.7 will still be released next summer, but 3.3 will be a
couple years out. There may not be a 2.8 - that's not decided yet.

In the mean time, the core developers are supposed to turn their
attention to the standard library. I think this is a good plan. It
will help with the migration to Python 3. Many new features in 3.1
are not being used, so the thinking is that the language itself does
not need to change so fast and let the various modules catch up (from
the standard lib and 3rd party). The hope is that by the end of the
moratorium, Python 2 will be old history and Python 3 will be used
almost exclusively.

The discussion just today on the Python-dev list is to hold off on 3.2
and 2.7 until the December 2010 time frame. The two year moratorium to
follow before 3.3 is released in like December 2012.
