MCVE Code Sample

I want to minimize the number of calls .item() within my data analysis. It often happens

  1. when putting a 0d-DataArray into a slice python da = xr.DataArray([0.5, 4.5, 2.5], dims=['x'], coords={'x': [0, 1, 2]}) da[: da.argmax()] -> TypeError: 'DataArray' object cannot be interpreted as an integer

  2. when using a 0d-DataArray for selecting python da = xr.DataArray([0.5, 4.5, 2.5], dims=['x'], coords={'x': [0, 0, 2]}) da.sel(x=da['x'][0]) -> IndexError: arrays used as indices must be of integer (or boolean) type

Both cases, I need to call '.item()'. It is not a big issue, but I think it would be nice if xarray becomes more self-contained.
