Everything will make sense to you when you look at the co-routines  
proposal, and note its authorship:

https://isocpp.org/files/papers/N4402.pdf

Visual C++ does not have an impressive track record of zippy adoptions of  
new C++ language feature. Most of the time it gets beaten to the punch by  
gcc. Weirdly, it was the first out of the gate with co-routines.

As I said: std::thread blows chunks on Windows. This was Microsoft's  
solution.
