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!","{""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",,1579956621
