Hmm, I'm not a fan of `Tensor[*Tuple[Any, ...]`. That's really verbose and inconsistent with existing standards. And it would require all type checkers to add support for open-ended non-homogenous tyes, which would be a heavy lift. Let's save that for another future PEP.
I was proposing that we simply extend the PEP 484 tensor convention to all variadic generic types. So this would be `Tensor[Any, ...]`.
