Long ago, I wrote<\/a> about using the PPL<\/a> to achieve a .NET 4.0 level of parity for async programming in C++. Since then, a lot of work has gone into raising this level of parity to .NET 4.5 and beyond. Introducing… C++ coroutines<\/a>.<\/p>\n

Sure, there have been various tricks<\/a> and extensions<\/a> to approximate this in the past. But this is actually ending up in the C++ standard<\/a>!<\/p>\n

Gor Nishanov<\/a>, a major champion\/designer of this new feature, describes coroutines as a negative overhead abstraction<\/a>, where you end up with something “not only simpler, shorter, neater, tighter than before, but also much faster.” (He also spends a good amount of time on the origins of coroutines via Melvin Conway, which I also previously wrote about<\/a>.)<\/p>\n

For a few practical samples, you can peruse the following resources:<\/p>\n
