Is your feature request related to a problem? Please describe.

The following doesn't work ``` python import xarray as xr

da = xr.DataArray([[1,2],[1,2]], dims=("x", "y")) da.stack(flat=...) ```

Describe the solution you'd like This could be equivalent to python da.stack(flat=da.dims)

I think using ds.dims it should be fine for datasets too.
