You can’t perform that action at this time.
The bitwise inversion operator on bool returns the bitwise inversion of the underlying int value; i.e. ~True == -2 such that bool(~True) == True.
It's a common pitfall that users mistake ~ as negation operator and actually want not. Supporting ~ is an artifact of bool inheriting from int. Since there is no real use-case for the current behavior, let's deprecate ~ on bool and later raise an error. This removes a potential source errors for users.
