Alex Waygood <[email protected]> added the comment:
Another option for code using Python <3.11, that will work without the `from
__future__ import annotations` import, is to do something like this:
```
from graphlib import TopologicalSorter
x: 'TopologicalSorter[str]' = TopologicalSorter({"a": {}, "b": {"a"}})
```
By using a string as the annotation, we give mypy the specificity it needs, but
the expression will never need to be resolved at runtime.
