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?","{""url"": ""https://api.github.com/repos/pydata/xarray/issues/2772/reactions"", ""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",,,13221727,issue
