I could give this a go, just a bit confused from reading the PEP:

# Unpacking using ``Unpack`` in older versions of Python
class Array(Generic[Unpack[Shape]]): ...

How does one access "Unpack" in older versions? from typing import Unpack only seems to work in python 3.11.

typing_extensions has an Unpack -- @tusharsadhwani might also be working on this one too

I'm working on it :D
