1975173557,PR_kwDOAMm_X85ee4vk,8406,Add getitem to array protocol,14371165,closed,0,,,0,2023-11-02T23:02:48Z,2023-12-12T20:54:00Z,2023-12-12T20:44:11Z,MEMBER,,0,pydata/xarray/pulls/8406,"Currently using getitem is not allowed for either a arrayfunction or arrayapi according to the type hints. Add support for it.

Issues found in #8344 as more and more typing was added. But getitem is used in main as well which should fail, but manages to pass due to lack of type hints:

Notes
* mypy will now complain for `_arrayapi[None]` or `_arrayapi([None,)]`, use `xp.expand_dims(_arrayapi)` for now instead.
