This is good in that it doesn't require any new bound identifiers.

I think readability suffers a bit because element names and text are
both strings.

If you want to pass a list of children as a parameter, there is also
no good serialization for it. Using a list is weak because it is the
same type as an element.

What about using constructor functions for elements? [HTMLDivElement,
'Hello ', [HTMLAElement, {href: '/'}, 'World']].
