Yeah. Java swing early on actually paused the event loop waiting for a second mouse click to return a double click. If I recall, some platforms would drop those events while paused, others would queue them. I think X dropped, windows didn't. this caused some workarounds smeared across the codebase. It's never going to be easy, and somebody has to pick the "right" answer. With more structure, you can get more consistency. I may not like the answers, but they're consistent answers and so I can reason about them. Reversible state transitions is a whole other bag of mixed metaphors. But I'd still say, more structure makes it consistent, and then you can reason about it, and then you can maybe solve some of those cases.
