I had not, but that is obvious now you say it. Thanks.

Where there isn't a more elegant solution, I'll use that. It might not
be elegant, but it's at least clear and expressive of the intent.

That still makes the name persist, so doesn't meet the requirements. It
also commits the further mistake of using a ‘__dunder__’ name style for
something that *isn't* a Python magic attribute.

Thanks for the attempt :-)
