[issue35098] Deleting __new__ does not restore previous behavior

[Steven D'Aprano]

Steven D'Aprano <steve+python at pearwood.info> added the comment:

I think the real WTF here is that you can write to arbitrary dunder attributes even if they aren't listed in __slots__.

py> Color.__NOBODY_expects_the_Spanish_Inquisition__ = "What?"
py> Color.__NOBODY_expects_the_Spanish_Inquisition__
'What?'

I think that assigning to Color.__new__ should have failed in the first place.
