Now that __array_ufunc__ has appeared in NumPy 1.13, we should be able to resolve a long-standing annoyance with xarray: the inability to use NumPy ufuncs like np.sin() directly on all xarray objects, such as xarray.Dataset.

I believe this could be straightforwardly accomplished by wrapping xarray.core.computation.apply_ufunc.

Some care should be taken to ensure that properly defer to other array types, as suggested in the NEP. This also could be a good time to resolve some of the xarray's broader consistency issues when interacting with and wrapping other array-like types.
