I expect that dealing with duck typing will be very high on the list of priorities for the future. In the meantime, for this specific use-case, you're probably not going to be able to statically check this type hint. Your choices would be:

- don't type check anything;

To be clear, for the moment this is what requests will do, unless the other maintainers strongly disagree with me (they don't). I am quite convinced that PEP 484 is insufficiently powerful to make it worthwhile for requests to provide 'official' type hints.

I suspect someone will provide hints to typeshed, and I certainly hope they're good, because if they're bad we'll definitely field bug reports about them (more on this in a different thread I think).
