[Python-ideas] Re: Allow user extensions to operators [related to: Moving PEP 584 forward (dict + and += operators)]

-1 from me. I can see someone not realizing an operator was changed, assuming it's standard semantics, and then having things break subtly. And debugging this wouldn't be fun either. To me this is monkeypatching without an explicit need for it, i.e. if you really want different semantics in your module then define a function and use that instead of influence-at-a-distance overriding of syntax.

This will also add a significant performance penalty to any code (even if you do not use any hooks). -1 from me too.
