PEP 594, take 2: Removing dead batteries from the standard library

[brettcannon]

@vstinner

I removed binhex and formatter after looking at PEP 594.

The docs for binhex are still there: https://docs.python.org/3.11/library/binhex.html#module-binhex . I will remove it from the PEP, though, as the module itself is gone.

When I removed asyncore, asynchat and smtpd

They seem to still be there, e.g., https://github.com/python/cpython/blob/main/Lib/asyncore.py and asyncore — Asynchronous socket handler — Python 3.11.7 documentation .

@gpshead

lib2to3 is listed as one to keep. That is already deprecated and removal is on track in its own bpo issue.

Removed!

@gpshead

It also suggests jumping directly to DeprecationWarning without a PendingDeprecationWarning release cycle first. Why?

That’s our deprecation policy: PEP 387 – Backwards Compatibility Policy | peps.python.org .

@gpshead

Cover that.

But it’s documented elsewhere as this is how things are deprecated, so since this is following policy I don’t think it needs to be explicitly called out.
