I still feel strongly that my proposal to reuse -*- from the “coding” declaration is a good choice for all the same reasons as ///, but also with the benefit of already being an in-use standard: PEP 723: Embedding pyproject.toml in single-file scripts - #139 by gwerbin
I actually think both 723 and 722 are useful and have legitimate places in the world. I tend to lean more in favor of 722 than 723, but that’s just my personal preference.
The point of my obnoxious re-posting of my own idea is that I care less about which one gets accepted, and more about avoiding the proliferation of new micro-standards that don’t interoperate with any others, serving only one particular limited purpose localized in time.
It seems like a surprising lack of restraint, uncharacteristic of the Python community.
