How to move childnodes of custom elements? Like slot's

[AndyOGo]

I'm curious if <slot>'s or similar functionality to React/JSX children is supported?

Like this example of <custom-element>, which has:

The following children (light DOM):

<custom-element>
  <span>This is some light DOM for custom-element</span>
</custom-element>

need to be properly slotted/injected into it's local DOM like:

<div>
  ${children} <!-- light DOM injection point -->
</div>`;

producing the following flatted DOM:

<custom-element>
  <div>
    <span>This is some light DOM for custom-element</span> <!-- light DOM injection point -->
  </div>
</custom-element>

slots are usually handled by custom elements and Shadow DOM, nothing different in hyperHTML, right?

Indeed, if the browser supports it though.

I'm more curious about children in general, if they work and if they get properly diffed incrementally?
