I guess what I had in mind is the case where both `x` and `y` are scalars, while `cond` is still a condition on `a`.  In that case you couldn't do `x.where(cond, y)`; it would require either `a.where(cond, x, y)` or `where(cond, x, y)` being supported.  Am I understanding that correctly?  (If I'm not being clear, consider a concrete case by plugging in e.g. `x=-2`, `y=0`, and `cond=(a.x + a.y < 5)`.)

`a.where(cond, x, y)` might seem odd, since it doesn't actually retain any of `a`'s values, but then it could retain coordinates and attributes, so it might still be useful.  And this differs from `where(cond, x, y)`, which it seems would retain `cond`'s coords and attrs.","{""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",,246502828

From their docstring:

>If both x and y are specified, the output array contains elements of x where condition is True, and elements from y elsewhere.

From your example above (haven't gone through the code), what you have implemented in this PR is a special case, namely the xarray analog to `np.where(a.x + a.y < 5, a, -1)`.

I recently had a usecase where this would be handy.","{""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",,246502828
