C++23 “Pandemic Edition” is complete -- Herb Sutter

image.pngC++23 is done!

C++23 "Pandemic Edition" is complete (Trip report: Winter ISO C++ standards meeting, Issaquah, WA, USA)

by Herb Sutter

From the article:

On Saturday, the ISO C++ committee completed technical work on C++23 in Issaquah, WA, USA! We resolved the remaining international comments on the C++23 draft, and are now producing the final document to be sent out for its international approval ballot (Draft International Standard, or DIS) and final editorial work, to be published later in 2023...

... Per our published C++23 schedule, this was our final meeting to finish technical work on C++23. No features were added or removed, we just handled fit-and-finish issues and primarily focused on finishing addressing the 137 national body comments we received in the summer’s international comment ballot (Committee Draft, or CD). You can find a list of C++23 features here, many of them already implemented in major compilers and libraries. C++23’s main theme was “completing C++20,” and some of the highlights include module “std”, “if consteval,” explicit “this” parameters, still more constexpr, still more CTAD, “[[assume]]”, simplifying implicit move, multidimensional and static “operator[]”, a bunch of Unicode improvements, and Nicolai Josuttis’ personal favorite: fixing the lifetime of temporaries in range-for loops...
