I 100% agree that this proposal is a bad idea. But I do have to play Devils

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.
True, it can do anything -- but if the thing it does is not related to
combining two things together and returning the result, people will be
surprised and consider it a bad function. (Or they should. ;-)
Foo.bar = 1 doesn't mean set bar to 1 but calling a dunder method.
But the `Foo.` tells us Magic May Be Happening, and we still expect something
reasonable to occur -- perhaps a boundary check, maybe a cache lookup, perhaps
a type change to an equal-but-different representation (1.0 instead of 1, for
example), or even setting other dependent variables.
