I've edited the example a bit for clarity, but I have no clue what's going on:

```python
import numpy as np
import xarray as xr

da = xr.DataArray(np.random.random((3, 4)),
                  dims=[""assets"", ""year""],
                  coords={""year"": range(2010, 2018, 2)},
                  name='var'
                  )

# Interpolate directly the DataArray
new_da = da.interp(year=[2011, 2015])
# Interpolate via dataset
new_ds = xr.Dataset({""var"": da.copy()}).interp(year=[2011, 2015])['var']

# Equivalent DAs
xr.testing.assert_identical(new_da, new_ds)

# Indexing works
xr.testing.assert_identical(new_da.loc[{""year"": 2015}], new_ds.loc[{""year"": 2015}])

# Assignment doesn't 
new_da.loc[{""year"": 2015}] = 42
new_ds.loc[{""year"": 2015}] = 42  # Fails 

---------------------------------------------------------------------------
