Contrary to what I said numpy is fine. If `x` is a DataArray

```python
np.array(x.mean())
# -> array(2.0)
np.array([x.mean()])
# -> array([2.0])
np.array(x)
# -> ok
```

`pandas` behavior is more surprising

```python
pd.Series(2)
# ok
pd.Series(x.mean())
# -> TypeError: len() of unsized object
pd.Series([x.mean()])
# -> dtype=object
# however for 1D x
pd.Series(x)
# dtype is fine
```

Something looks a bit odd to me. But it looks more like a pandas issue","{""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",,274996832

I'll try to find a good spot in the doc to write a line or two about this.","{""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",,274996832

This is nice from an consistency perspective: every operation on an xarray object returns another xarray object. Also, as you point out, this allows us to preserve metadata such as attributes or scalar coordinates.

I'm going to mark this as a documentation issue: this would be a great thing to add our docs somewhere (maybe the FAQ page?).","{""total_count"": 1, ""+1"": 1, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",,274996832
