One other point here. The motivation for the PEP is weak - it’s an argument that certain behaviour is “not obvious” and therefore should not be allowed. And furthermore, the survey of other languages (thank you by the way for adding that) seems to imply that most other languages handle this in style guides.
Is there any example in real world code (a bug report on a project on github, for example) where use of this construct caused an error in the project? That would be a better argument (although a single example would still be very weak - to be compelling you’d need to show that this mistake causing bugs was a relatively common occurrence).
