await / coroutine

Hi!

Anyone working on the coroutine implementation described in https://isocpp.org/files/papers/N4402.pdf ?

Thank you a lot for the attention!

Best regards

Discussion on the ISO C++ list[1] suggests that Gor Nishanov of Microsoft is working on a clang implementation. However, I'd be much more interested in seeing how efficient one could make suspend-down coroutines (like Boost.Coroutine) if you had compiler support for it. If I could only have one of suspend-up or suspend-down coroutines, I'd much prefer the latter.
