sense because numpy and pandas both have it as a method, but the @ operator
is a really a cleaner way to express this now that we're Python 3 only.
(Speaking of which, why don't we support @ in xarray yet? :).)

One question: how should these functions align their arguments? Recall that xarray does an `inner` join for arithmetic (though there's an option to control this), and an `outer` join in most other cases. It's not entirely obvious to me what the right choice is here (or if it really even matters).","{""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",,396102183
