I was actually physically close to YGLF but unable to attend, I spoke there at a previous year. Michel is a friend and I collaborated with him on MobX. He's also one of the nicest people I know and he visits often. I think you might want to check out WPF + PostSharp for something very similar to this approach in C# land. I definitely think it's the right approach for reactivity.
