I think it could totally fly with a language with good declarative support. Why learn separate syntax (html, css) when all you need is some declarative semantics?

Clojure has this sort of thing and any other homoiconic language gets it for free.

Thanks, that is my thinking: learning three separate languages is a big burden, especially on beginners.

You would need to know them a bit at least - for debugging.
