I 100% agree that this proposal is a bad idea. But I do have to play Devils
advocate here.
The the-code-is-understandable-at-face-value ship has already sailed. + doesn't
mean add, it means calling a dunder function that can do anything. Foo.bar = 1
doesn't mean set bar to 1 but calling a dunder method. In python code basically
can't be understood at face value.
