Standard C++ is still lacking standardized future continuation. Boost has “experimental” implementation that is 11 years old. In the meantime, at least three major proposals were brought before the standard committee, but none made it into the standard. Current proposal is 190 printed pages long. The earliest it can become standard is C++26, and even that is not guaranteed. Such glacial speed of change results in a lot of confusion and feature lag behind other languages. C# had continuations since 2010, and JavaScript since 2015 (EC6). While C++ 11 was relatively on par with the industry when introducing futures, current C++ is quite behind the crowd. “Experimental” code should not stick around for over a decade in any library, and especially in a semi-standard library like Boost. There must be a way to solve problems faster.
