``` In [1]: import xray

In [2]: ds = xray.Dataset({'x': range(5)})

In [3]: ds['x'].values[0] = 9999999

In [5]: ds Out[5]: <xray.Dataset> Dimensions: (x: 5) Coordinates: * x (x) int64 0 1 2 3 4 Data variables: empty ```

Instead, ds['x'].values should return a read only numpy array, to ensure that an error gets thrown.
