Yeah it's not perfect, but it often works well enough. Just another benefit of isolating code into stateless stuff. One use case I have is for instance debugging a bug that's hard to trigger. When it finally happens and my breakpoint is hit, I can edit the code, hot swap it live, drop the current frame and then make it call my updated function again as if the original call never happened.
