We should be constructing from the type of `v`. `pd.Index` also has a method `_shallow_copy` IIRC we could call,"{""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",,522402552

where the index gets piped through `pd.Index` (even if it is not renamed):

``` python
import pandas as pd
pd.Index(ds.indexes['time'])
```
returns an `Index` instead of a `CFTimeIndex`","{""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",,522402552

```python
print(
    ds.indexes,
    ds.rename().indexes,
    ds.rename_dims().indexes,
    ds.rename_vars().indexes,
    sep=""\n"",
)
