The writeup is written very well. Kudos! However, I really wonder if this scales to real applications… I’ve seen too many people get initially mesmerized by “event driven” programming only to find the system eventually becomes a steaming mess that nobody can comprehend or debug. Or it manages to work but has serious performance issues (in an exclusively “push” design)… Maybe in a single process, single threaded environment, it is more difficult to screw up?
