Yes, it's worth discussing. I don't know if there will be a satisfying resolution, though.","{""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",,1217425815

Ideally NumPy ufuncs would be typed to check for `__array_ufunc__`. Something like:
```python

It makes me think it may be coming from xarray, since it's not just `np.exp(series).rename(""blah"")` which is raising.

But I'm not sure _where_ it would be coming from. Our `__array_ufunc__` isn't typed...!","{""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",,1217425815

My guess is that the `""ndarray[Any, dtype[Any]]""` type signature is from `np.exp`. Do you know whether we get the same result with another library's `__array_ufunc__`'s arrays, with that library's equivalent `rename` method?","{""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",,1217425815
