feature: anonymous templ functions

[thisguycodes]

func test() templ.Component {
	comp := templ() {
		<div>content</div>
	}
	return comp()
}

For a less contrived use case: I want to attach some metadata to my pages, basically frontmatter, and it'd be nice to be able to do things inline.

Right now, this works:

templ myPage(fr pagedb.Front) {
	if fr.Bool("isReal") {
		<div>I'm a real boy!</div>
	} else {
		<div>sadly just a puppet...</div>
	}
}

func init() {
	pagedb.Register(myPage(), map[string]any{
		"meta": "data",
		"isReal": false,
	})
}

But being able to put it inline would unlock a few things when it comes to mimicking the workflow / format of other frontmatter site systems.

I'm in favour of this feature. I think it solves a few slightly annoying things when building things with templ. Including components that take a component param:

templ MyPage() {
  @layout(templ() {
    <script>....</script>
  }()) {
    // page contents
  }
{
