Doesn't matter, the point was what C subset does C++ support today.

C++20 designated initializers must be specified in definition order, whereas they don't in C99.

In your example,

    Point point = {.z = 2.0, .x = 1.0};
produces a compilation error. This is annoying, but workable. And at least it's a compile-time error, rather than a bug that perniciously sneaks into production.

Why do you think I wrote "A subset of designated initializers is supported in C++20."?
