Would it make sense to pack them?

``` python
if isinstance(objects, (xr.DataArray, xr.Dataset, dict)):
    objects = [objects]
```
Because the alternative is to raise and then the user has to do `[objects]` himself, which seems a bit nonsensical to me. Although it is also nonsensical to pass a single `DataArray` or a `Dataset` to `xr.merge`, in contrast to `dict`.

Then we would need to check `isinstance(obj, (xr.DataArray, xr.Dataset, dict))` in the in the `dict_like_objects`-loop and if not raise a `ValueError`?","{""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",,441341354
