Some sort of coroutine solution is definitely on my list too. I'm actually not too passionate about which one it is, except for a distaste for async/await on the grounds the compiler ought to be able to do it for me. But generators, threads or actors cheap enough to use freely, coroutines, something that allows me to break out of the strictly hierarchical structured programming system and retain some degree of state within a function when I need to. It's possible to hack something together in a language lacking this, by moving all function state into a struct/object but all the manual scaffolding is painful and error prone.
