I was confusing dimension names and variable names. I would support raising or falling back to a reasonably sane default -- the reason I stumbled on this was having a None coord name was breaking the _repr_html in Jupyter and causing a much more confusing error message,"{""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",,873713013

Turns out arrays in numpy 1.15 don't have `__array_function__`. So this:

```python
   if deep:
        if hasattr(data, ""__array_function__"") or isinstance(
            data, dask_array_type
        ):
            data = copy.deepcopy(data)
        elif not isinstance(data, PandasIndexAdapter):
            # pandas.Index is immutable
            data = np.array(data)
```

could just be

```python
   if deep and not isinstance(data, PandasIndexAdapter):
        data = copy.deepcopy(data)
```

But I'm not familiar with `__array_function__` or why it's being used here, any thoughts?","{""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",,686495257
