It looks like all the `combine` functions expect lists of Datasets, not DataArrays (see docstrings).

It should be relatively easily to make this work like `merge` which can take a list of `Datasets or DataArrays`. See this code in `merge`:
https://github.com/pydata/xarray/blob/756c94164840e8c070bcd26681b97c31412909ae/xarray/core/merge.py#L593-L602

`to_dataset` will fail for unnamed DataArrays, but `_to_temp_dataset()` will succeed. It seems to me like we want lists of unnamed DataArrays to work (like in the first example), so call `_to_temp_dataset` when needed. Maybe @shoyer has an idea on how to implement that cleanly.

1. If `combine` receives a list of unnamed DataArrays, we convert them to temp datasets and then pass datasets down to merge.

2. If `combine` receives a list of  named DataArrays, then merge will do the right thing.

3. If `combine` receives a list containing both Datasets and unnamed DataArrays then merge will raise the right error.

So really it's just (1) that needs a special case in the combine functions?","{""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",,484270833
