I like shoyer's
> vectorize format() over each element of the array (the proposal in the linked numpy issue)  

as I feel it more consistent with the existing xarray `__repr__`.

I sometimes want a 0d-dataarray to behave as a native scalar.
`format` is one of a typical case, but there are several other cases, e.g.,  `np.ones(xr.DataArray([0])[0])`.
Therefore, I always needs to be carefule whether the scalar is xarray object or not.

I am a bit worrying if printing 0d-dataarray as a scalar would confuse me as it is a scalar not a 0d-array.

I guess there are two possible behaviors for `'{:d}'.format(x)` where `x` is a DataArray object:
- coerce scalar arrays to native Python numbers and format it like a `float`
- vectorize `format()` over each element of the array (the proposal in the linked numpy issue)

These behaviors would definitely conflict for scalar objects -- in the second case, we would still want to include some indication that it's an `xarray.DataArray`. NumPy doesn't have a conflict because indexing an array results in a NumPy scalars, which prints like Python builtin scalars.","{""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",,415209776

However, I'm a bit worried whether it would be surprising if an object that looks a native scalar is actually an xr.DataArray of one element, especially when working in an interactive environment.
