True, but its neatly encapsulated  in one place. And if we are going to support many Index classes that build on numpy, scipy, then support for pandas indexes seems entirely in-scope.

> I'd just want to add that, from my experience with debugging multi-index issues, it is hard even for advanced users to see what's going wrong when coordinates and indexes are not consistent.

Should we expose `xr.tests.assert_internal_invariants` for debugging?","{""total_count"": 1, ""+1"": 1, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",,1422543378

 I like the last spelling: `ds.assign_indexes(indexes)` though that raises a few questioins:
1. does `indexes` get merged with existing `._indexes`? 
2. If not, how does a user merge manually? Can we extract enough information from `Index` to have `xr.merge(Indexes) -> Indexes` work?","{""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",,1422543378
