> Personally I judge code quality by a) Functionality (does it work, is it safe?), b) Readability c) Conciseness d) Performance and e) Extendibility, in this order, and I don't see how these new features in reality help move any of these meaningfully in the right direction. I don't understand... How do these features not address those points? > a) Functionality (does it work, is it safe?) constinit, consteval and all the remaining constexpr improvements are a massive step for ensuring the "compile-time-ness" of code: https://oleksandrkvl.github.io/2021/04/02/cpp-20-overview.html#constinit https://oleksandrkvl.github.io/2021/04/02/cpp-20-overview.ht... https://oleksandrkvl.github.io/2021/04/02/cpp-20-overview.html#constexpr-features https://oleksandrkvl.github.io/2021/04/02/cpp-20-overview.ht... There's several more sharp edges being removed too. It's of course not going to tackle the fundamental safety concerns the way Rust is doing, but that would be a new language (like Rust is) anyway. > b) Readability requires is infinitely more readable than the SFINAE we had to write so far: https://oleksandrkvl.github.io/2021/04/02/cpp-20-overview.html#concepts https://oleksandrkvl.github.io/2021/04/02/cpp-20-overview.ht... Besides that elephant in the room, most of these changes involve making the code either simpler to read/write (too many to name) or more explicit (consteval/constinit, attributes, ). > c) Conciseness Half the features contribute to this in one way or another (e.g. see previous point, or the spaceship operator), but there's also a whole list of syntactic sugar being added: https://oleksandrkvl.github.io/2021/04/02/cpp-20-overview.html#sugar https://oleksandrkvl.github.io/2021/04/02/cpp-20-overview.ht... > d) Performance What about coroutines? https://oleksandrkvl.github.io/2021/04/02/cpp-20-overview.html#coroutines https://oleksandrkvl.github.io/2021/04/02/cpp-20-overview.ht... > e) Extendibility Various fixes to customization points: https://oleksandrkvl.github.io/2021/04/02/cpp-20-overview.html#fix-structbind-cp https://oleksandrkvl.github.io/2021/04/02/cpp-20-overview.ht... https://oleksandrkvl.github.io/2021/04/02/cpp-20-overview.html#fix-range-for-cp https://oleksandrkvl.github.io/2021/04/02/cpp-20-overview.ht...
