Thanks for the report @derhintze. I agree this seems like a bug. I'm a bit confused by this actually. Our __getitem__ implementation is here:

https://github.com/pydata/xarray/blob/7683442774c8036e0b13851df62bda067b2a65d5/xarray/core/dataset.py#L1418-L1441

and the keys view of a dataset is not hashable:

python isinstance(d.keys(), typing.Hashable) False

Which should be triggering the second @overload in the code above. So I'm not sure what's going on!
