Rendering nested children

Hi folks,

if I am rendering an element, I know I can render children by specifying them in the tagged html like this:
html`<wb-content><wb-child/></wb-content>`

What is the right way to do this if the number and type of child elements is not known until runtime? I've been creating each as a one-off, but that doesn't seem right (and is especially annoying since heresy doesn't have html.node for one-offs).

Imagine turning JSON content into tags, for arbitrarily-deep JSON.

Or is heresy the wrong tool for that?

Thanks!
