I think improving the error message is the way to go.

The main issue is that right now we sort `Dataset` dims and would need to be able to convert the keys to something comparable. See also #2173, where I suggested to convert to `str`. This might be too naive for immutable objects without a custom `__str__` / `__repr__`, so something like this, maybe:
```python
sorted(self.mapping, key=lambda k: (type(k).__qualname__, str(k)))
```
which would group objects with the same type name together","{""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",,856900805
