While digging into the code, I found an undocumented way of doing it:

```yaml
facets: [""Facet for a column"", {""array"": ""Facet for an array""}]
```

The only remaining problem with that solution is here: https://github.com/simonw/datasette/blob/250db8192cb8aba5eb8cd301ccc2a49525bc3d24/datasette/facets.py#L33

We have:

```python
type, metadata_config = metadata_config.items()[0]
```

But it requires to cast the `dict_items` as a list prior to access the first element:

```python
type, metadata_config = list(metadata_config.items())[0]
```

I guess it's an unspotted bug? (I mean, independently of the facets-with-arrays issue.)","{""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",1078702875,
