Please correct me if I'm wrong, but I think the approach of your final paragraph could be very straightforward to implement in Elm (a purely functional language that also has one of the best implementations of FRP that you can find anywhere, in any language). See this article on "the Elm architecture", which I think could be very naturally extended in the way you propose: https://github.com/evancz/elm-architecture-tutorial https://github.com/evancz/elm-architecture-tutorial Elm's approach involves having completely declarative, purely functional UI code (with efficient update computations resolved via a virtual DOM in the background), where individual components are highly composable and referentially transparent.

In terms of just web programming, Elm is amazingly close to my dream. I have some beefs with the language (Ports are unintuitive, generics higher kinded polymorphism are non-existent, haskell syntax), but they are pretty small beans. The big part that I find missing is the cross platform abilities (I'm talking web, mobile, and desktop platforms without the slow/hacky do-everything-in-html5 methods). And to be honest, if I were to start from scratch, I'd probably be re-implementing 90% of Elm anyway. Which maybe says to me that instead of starting from scratch, I should just join the Elm community and start hacking on the compiler backends (for compiling to platform-native code) and front end libraries (to target native UI framework code), and hope the language grows closer to what I would like.
