Allow using templ components in templ component scripts

[fbuedding]

I think it would be cool and practical to allow using templ components in templ script components.

In my opinion it would be especially useful for native web components.

Simple example:

templ todoItem(text string){
 <li> { text } </li>
}

templ todoList(){
<ul id="todo-list">

</ul>
<input type="text" id="todo-input"/><button onclick={ addTodo() }>add</button>
}

script addTodo() {
const itemText = document.getElementById("todo-input").value;
const item = @todoItem(itemText); //  maybe just render the component to a javascript function, which returns the component either as a string or as a HTML component 
const list = document.getElementById("todo-list");
list.appendChild(item);
}

This also would make code formatting much easier, since one wouldn't have to create those inline elements as strings.

PS: I love this project! :)
