Didn't expect this to throw errors.

Issue: AttributeError: partially initialized module 'anndata' has no attribute 'AnnData' (most likely due to a circular import)
I'll have a look.

[ivirshup]

There are going to be a lot of strings used for type annotation because they would otherwise be circular imports. Basically, functions which operate on AnnData objects, which are used in AnnData methods. This may be solved once we can bump minimum python to 3.7 and use from __future__ import annotations, which should be reasonably soon (May-ish?, next major release)

[Zethson]

Ahh, I see. That's why they were strings before. I was already wondering.

This is obsolete, we use Ruff now
