Show HN: Coros – A Modern C++ Library for Task Parallelism

Is there a way to prevent callback hell in C++ when doing asynchronous communication with C++ before 20? Coroutines seem to be the only clean solution. Promises can work, but they tend to be difficult to reason about if branching is involved.

Traditionally the way to prevent "callback hell" is to use something like async/await syntax. Without that there aren't a ton of good options. Like you mentioned, you could switch to promises with polling.

There are library-only stackful coroutines options, like in boost.
