C++17 already has parallel algorithms. Executors (P0443, hopefully in C++23) will add asynchronous execution to parallelism. The usual C++ error handling approach, exceptions, will not work “out of the box.” We need to build up new patterns for error handling.

C++ parallel algorithms and executors have …
