Python Language Moratorium

By Deane Barker on November 9, 2009

PEP 3003 — Python Language Moratorium : Python has announced a moratorium on language changes to let alternative implementations catch up to the core C implementation.

This suspension of features is designed to allow non-CPython implementations to “catch up” to the core implementation of the language, help ease adoption of Python 3.x, and provide a more stable base for the community. [The idea is to] slow the alteration of the Python core syntax, builtins and semantics to allow non-CPython implementations to catch up to the current state of Python, both 2.x and 3.x.

Python, as a language is more than the core implementation — CPython — with a rich, mature and vibrant community of implementations, such as Jython, IronPython and PyPy that are a benefit not only to the community, but to the language itself.
