Are Boost.coroutine2 coroutines still relevant now we have c++20 coroutines ?

  `std::execution`, the proposed C++ framework for asynchronous and parallel programming.

  

Coroutine task types and other awaitables are well supported by the P2300 std::execution proposal. Take a look at https://github.com/NVIDIA/stdexec Coroutines in general are good at suspension and resumption, but they need a place to run and something to resume them. That's what the sender/receiver framework provides.

  Boost.Coroutine2

  

Was boost.coroutine2 ever relevant? I believe its performance has never been good enough to make this library useful in production code. Several years back when I checked it out, I found that its implementation threw and then caught an exception on coroutine exit. The author told me it was by design. There ended my interest in boost.coroutine2.
