TODO / Ideas

// Yield function with name of HTML tag
function Nav(links) {
  yield html`<nav aria-label="Primary">`;

  yield function* ul() {
    for (const link of links) {
      yield NavLink(link);
    }
  };

  yield html`</nav>`;
}

// Yield function with name of landmark
function Page() {
  yield PrimaryNav();

  yield function* main() { // <main>
    yield Heading("Welcome!");
  }

  yield function* contentinfo() { // <footer role=contentinfo>
    yield FooterLinks();
  }
}

// Perhaps allow attributes to be set
function Nav2(links) {
  yield function* nav() {
    yield attributes({ "aria-label": "Primary" });

    yield function* ul() {
      for (const link of links) {
        yield NavLink(link);
      }
    };
  }
}
