[New-bugs-announce] [issue46298] Automatically check for __slots__-mistakes in Lib

[Arie Bovenberg]

New submission from Arie Bovenberg <a.c.bovenberg at gmail.com>:

Recently, I've identified some __slots__-related mistakes in the stdlib (bpo-46247, bpo-46244, bpo-46246).

Looking forward, it'd be wise to automate this check so mistakes don't creep into the code in the future.

Implementation-wise, the most straightforward solution would be a single test that walks all Lib/ (sub)modules and checks all classes.

Perhaps those with more experience in the test suite can chime in where this check might live
