I added minor comments but my competence with Python is very limited, so please feel free to ignore them if they are irrelevant or wrong

Would it make sense to use type annotations for both the parameter and the return type?

I wouldn't know how to properly type them

If the type_args are more than one should we throw an exception perhaps?
If not, I would add a short document to explain it

Also here I would consider adding type annotations

In Python I often get confused by is because I should use isinstance instead. I am not sure if that is the case here, but I mention it to be on the safe side

is is Java's ==
== is .equals
isinstance is instanceof
Here, we want to check if the type is exactly ReferenceByName

when there are many parameters and several of them are boolean, we could pass them by name to avoid possible issues (i.e., writing them in the wrong order)

Should we mention this in the README?

Mention what? The algorithm for getting the annotations?
