alt Hacker NewsHalf-serious reason: because with each C++ version, we seem to get less and less what we want and more and more inefficiency. In terms of language design and compiler implementation. Are we even at feature-completeness for C++20 on major compilers yet? (In an actually usable bug-free way, not an on-paper "completion".)
The compiler design is definitely becoming more complicated but the language design has become progressively more efficient and nicer to use. I’ve been using C++20 for a long time in production; it has been problem-free for years at this point. It is not strictly complete, e.g. modules still aren’t usable, but you don’t need to wait for that to use it.
Even C++23 is largely usable at this point, though there are still gaps for some features.
