I try to ignore implementation details like that. Heck, I still don't fully trust dictionaries to be ordered! I removed the WIP. We can deal with the concat dim default object separately, including turning it into a ReprObject (not exactly sure what the advantage of it is over just using the string, but, meh).","{""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",,396008054 https://github.com/pydata/xarray/pull/2648#issuecomment-451583970,https://api.github.com/repos/pydata/xarray/issues/2648,451583970,MDEyOklzc3VlQ29tbWVudDQ1MTU4Mzk3MA==,291576,2019-01-04T22:12:44Z,2019-01-04T22:12:44Z,CONTRIBUTOR,"Is the following statement True or False: ""The user should be allowed to explicitly declare that they want the concatenation dimension to be inferred by passing a keyword argument"". If this is True, then you need to test equivalence.
