Sure. To keep the same form since the children are static, in Solid you could write:

const UnorderedList = ({ children }) => (
  <ul>
    {
      children.map(child => <li>{child}</li>)
    }
  </ul>
)
const App = () => (
  <UnorderedList>
    <a href="http://example.com">Example</a>
    <span>Example</span>
    Text
  </UnorderedList>
);

However, assuming general purpose that would optimize for dynamic children I’d use Solid’s For Component:

const UnorderedList = props => (
  <ul>
    <For eacb={props.children}>{
      child => <li>{child}</li>
    }</For>
  </ul>
)
