If this receives positive feedback on typing-sig I would definitely sponsor it. But I'd first like to have the discussion there (and the time to read it). (FWIW I would prefer the discussion to happen on typing-sig, not python-ideas.) On Wed, Oct 7, 2020 at 7:04 AM Chris Angelico wrote:

Hi all,

Something that's on many of our wishlists is support for variadic

generics. Here's a first draft of a PEP detailing how they might work.

Does the "many" there include any core devs who would sponsor your PEP? If so, the best way to move forward would be to get someone to sign off on it, and actually publish it as a proper document.

Generally looks good to me, although the name ListVariadic seems a bit jargony (and worse, appears to be jargon imported from another language). I think something like TypeListVar would be clearer.

Agreed. (I was just about to write my own comment saying the same thing.) I was thinking "TypeVarList" originally, but I also like "TypeListVar". -- David Foster | Seattle, WA, USA Contributor to TypedDict support for mypy
