Unpack vs Expand

[q0w]

Is Unpack[TypedDict] for annotating kwargs is a temporary workaround until Expand will be implemented in both mypy and pyright?
Why Unpack is allowing for **, when is for only * or am I missing something?

[JelleZijlstra]

Unpack[] was introduced by PEP 646 for *args. That is currently its only standardized use. An upcoming PEP, PEP 692, will allow using it for **kwargs too. Pyright already has experimental support for this feature.

Expand is a name that has been floating around in some proposals and in an unmerged mypy PR, but to my knowledge it has not been implemented in any type checkers. I do not expect it to become standardized.
