1016576623 PR_kwDOAMm_X84stU8v 5839 Dataset.__setitem__ raise on being passed a Dataset (for single key) 35968931 closed 0     1 2021-10-05T17:18:43Z 2021-10-23T19:01:24Z 2021-10-23T19:01:24Z MEMBER   0 pydata/xarray/pulls/5839

Inspired by confusion in #5833, this PR slightly clarifies the error thrown when the user attempts to do ds['var'] = xr.Dataset. The original error is TypeError: cannot directly convert an xarray.Dataset into a numpy array. Instead, create an xarray.DataArray first, either with indexing on the Dataset or by invoking the `to_array()` method. while the new error is TypeError: Cannot assign a Dataset to a single key - only a DataArray or Variable object can be stored under a single key.
