You'd probably like Clojure. As an aside, though, part of the reason we have different languages for things like backend code, markup and styling is that they're commonly done by different people with different specialties. A general-purpose language will not offer much benefit to a designer, but it will trip them up more often. Having a language tailored to your specialist is a good thing. The only time you'd really want everything done in one language is when the same coders are doing everything. I admit I'm in that situation very often, but it's more maintainable if you just use CSS or similar so that normal front-end guys can work with it.
