This was dead when I saw it, which is weird because it's factually true. So I vouched for it.

Herb Sutter proposes a bunch of stuff to WG21 (the C++ committee) and most of it goes nowhere. We're not talking about two proposals here, maybe a dozen is closer. Most of that stuff from many years is in Cpp2 because it's Herb's language so they can't stop him.

The one thing Herb proposed in that time which got into C++ was the spaceship operator <=> which is basically like Rust's PartialOrd trait, you write one operator for your type, and for any pair of values (this & that) you decide whether this was Greater, Equal or Less than that -- or none of the above. As a result the compiler can implement all the obvious comparison operators like <= or == or > using that one piece of code you wrote, and it's easily able to be consistent. This is very nice, and it's in C++ today, but it's also in Cpp2 of course.
