410317757 MDU6SXNzdWU0MTAzMTc3NTc= 2772 Should xarray allow assigning a masked constant? 500246 open 0     1 2019-02-14T14:10:20Z 2019-02-15T20:24:44Z   CONTRIBUTOR      

Currently, ds['a'] = ((), ma.masked) where ds is an xarray.Dataset gives ValueError: Could not convert tuple of form (dims, data[, attrs, encoding]): ((), masked) to Variable., whereas ds['a'] = (), ma.MaskedArray(0.0, True) works (it sets the indicated value to NaN). Should assigning ma.masked be equivalent to assigning ma.MaskedArray(0.0, True), or are there good reasons for the difference in behaviour?
