Bug report

The type stub for django.test.ContextList is incomplete.

What's wrong

https://github.com/typeddjango/django-stubs/blob/master/django-stubs/test/utils.pyi#L44-L46

Is missing __getitem__(str) and __contains__(str). Technically, get(int) is also missing.

I also think that the type default: Optional[str] for get is wrong and should be either Any or Optional[Any].

How is that should be

I suppose a full interface could look something like that: https://mypy-play.net/?mypy=latest&python=3.10&gist=f736dc3a1c40b8ddfa2e15900c0aac53

Although I find it questionable, whether we even want to reveal the full implementation based on list, or maybe actually just go with something like Mapping[str, Any] (Actually mapping isn't entirely correct either because it implies Collection[str]. So more like a custom class that does not inherit list and has only __getitem__(str), __contains__(str) and keys(str).

## System information

- `django-stubs` version: [33d4dc7](https://github.com/typeddjango/django-stubs/commit/33d4dc7dae8fb825d3804887a14d7594dc655abf)

Looks like it has been (mostly) fixed by #1100 . The interface is a bit simpler than my suggestion. Not sure if that has any practical significance though.

Unfortunately I can't fully test with our complex codebase because of another blocker.

[I'll leave the decision to close to the devs.]

I'll close this for now. Feel free to reopen or reply if you're able to test and there are still issues.
