> some synchronous-looking piece of code doesn't run synchronously so some state at the beginning of the function has a different value at the end of the function Does function coloring solve this? I don't think it's the case. Python, JS, etc. don't see this issue much because the interpreters tend to be single threaded or have GILs. C#, for instance, would see all the same issues a Java or Go program might with respect to variables changing over time.
