I know this has come up in the past.

Could the consensus have changed regarding bool's inheritance from int?

This is not intuitive (to me), and recently bit me as a bug:

Python 3.9.1 (default, Dec 13 2020, 11:55:53)

[GCC 10.2.0] on linux

Type "help", "copyright", "credits" or "license" for more information.

>>> {1,True}

{1}

I've worked around it by storing tuple(type, value) in the set, which is fugly. Yes, I need mixed types in the set, and I'm using the set for efficient lookup.

A contrived example I dreamed-up, which I also find non-intuitive:

>>> x = {}

>>> x[True] = 1

>>> x

{True: 1}

>>> x[1] = 1

>>> x

{True: 1}

Maybe a wish list item for Python 4.0?
