This works for me:

```js
return html`
<${React.Fragment}>

Quiz

${entriesUi}

---

<${Summary} entries=${entries} />

`;
```

If I don’t wrap the fragment around the roots, I’m getting this error:

> Warning: Each child in a list should have a unique "key" prop.

(That is, HTM seems to return an Array and not a fragment.)

If my suggestion doesn’t make sense, then it may be helpful to support the `<>...` syntax for fragments.
