Oh certainly, it's just beyond what I can do as a C library. I've also seen another approach that implemented a customized libc replacement to allow this to work. But that and modifying the compiler itself are really extreme steps. It's still doable, and it's definitely worth doing, but I understand the uses I've mentioned are rather niche, so it's unlikely to occur. For one, we still don't have built-in stackful coroutine support even in C++20.

> modifying the compiler itself are really extreme steps Yes, it's not for the average developer. Yet it should be incumbent on the tools builders. I'm actually surprised that most compilers/interpreters don't have a "step backwards" flag that you can turn on during compile/run-time. It would be a helpful feature to expert and novice developers alike, but hasn't really caught on outside of niche areas.
