I have read much about Fibers since they were introduced and have never come up with a real use case.

All the examples I find are like the trivial ones here where it just feels like instead of jamming a bunch of code into a single messy function that yields, you'd be better off particularly from a static analysis standpoint just having ordered method calls or chained callables where each step returns the next step as a callable.

I've yet to see a use case where I can't come up with a safer way to do it without Fibers, but I would love if someone could enlighten me because I feel like I am absolutely missing something.

I once had a use case where I wrapped a callback based library (Amazon's S3 library I think) call to instead return an iterator. Couldn't do that with only a generator since you can't yield in the callback itself. And it wasnt possible to write a custom iterator class since the library didn't give you back control until it was done.

That was the first and only time they were kinda useful to me.
