> Given that in 3.x every stdlib module is supposed to be in Python with an optional C accelerator,
Is this written down somewhere? And when was that policy decided?
When we added math.is_close() (
https://www.python.org/dev/peps/pep-0485/) someone (Victor Stinner?) re-wrote the math module as a Python wrapper around the C one, so we could add pure Python functions to it. But that was rejected, and we stuck with pure C for that one.
