Is the other mypy warning new as of 0.981?

Perhaps the return type should be Any instead of T?

[maresb]

Ah, or should DictToArrayBijection be a generic on T?

EDIT: I got confused here, this should instead refer to Compose.

[lucianopaz]

Looks like returning Any did the trick.

I ran pre-commit on all the files and that was the only new warning that popped up.

[maresb]

I'm thinking that Compose should be a generic

[maresb]

Suggested change

	def __call__(self, x: RaveledVars) -> Any:
	def __call__(self, x: RaveledVars) -> T:

[maresb]

I think you should change class Compose: above to class Compose(Generic[T]):. This way, the T variable from __init__ and __call__ will be linked, and the type variable will actually define a relation.

Thanks @maresb! The Generic[T] class annotation fixed the type hints
