Message 108126 - Python tracker (original) (raw)
My understanding is that the desire to have pure python versions of standard library modules is to decouple the standard library from dependency on CPython as far as practical. Perhaps all existing Python implementations have dealt with datetime somehow, but what about new implementations? Having a pure Python version would help developers of new implementations get started, even if they later decided to reimplement it more natively (as CPython has done).
