Something similar (and less of a parentheses hell) is Scalatags by the amazingly prolific scala programmer lihaoyi. The good things about Scalatags is that the same code can be used both in the backend and in the frontend. (I don't use scala on the backend anymore but Scala.js is really good!)

In one of my current projects, I'm using Scalatags on the server-side generating strings, and then using the same templates on the client to generate Preact.js vdom nodes to re-hydrate the server side templates. Cross-platform, cross-backend templates is really a very nice thing to have!
