When running this code:

``` python
import xarray as xr
ds = xr.tutorial.load_dataset(""rasm"")
ds.rename({""time"": ""time""})
```

I will get the following warning:
``` python-traceback
UserWarning: rename 'time' to 'time' does not create an index anymore. Try using swap_dims instead or use set_index after rename to create an indexed coordinate.
  ds.rename({""time"": ""time""})
