An exploration of designated initializers and named field initialization across C, C++20, Zig, Rust, and D, focusing on field order and construction.
C++20 formally supports designated initializers somewhat in the style of C99. Here, I discuss field order and issues around construction and destruction in C and C++ as well as Zig, Rust, and D. I also give a quick rundown of C++20 features in the recent GCC 10 release.
