I'm interested in <i>exactly</i> the sort of application framework they seem to be talking about. This is really how web apps (or all apps) should be built.<p>The Wikipedia link isn't terribly informative, but there's a ton of more relevant literature tied in with functional reactive programming. (That's the FRP in their to-do list). In particular, there's a research project called Flapjax that you can play with right now that drives home how nice it <i>could</i> be to program in this paradigm.<p>I have two worries about Luna, though. It doesn't look like they're using a nice type system, which will be a pain for larger apps. And I can't say I like that "Finish patent documentation for incremental computing framework" to-do item.
