  That was the point 20 years ago. These days it is pivoting to compile time functional programming

    What does that mean ?

      If you have a constant expression like 1 + 2 in your code you can evaluate it at compile time once and avoid computing it at runtime. You can do that with control flow and much more complex language constructs in C++. If you want to know more about that look into C++ template meta programming, constexpr, and constval.

        Or don’t look into those things if you wish to remain sane

        Translation: “We’ve made the preprocessor a first-class language feature!”

      Overengineered mess

    C++ has a lot of terrible language features because it would allow some 8 bit embedded CPU to dynamically change from LSB to MSB ordering in the middle of decoding some input. 🙈

    does anyone actually follow whatver the comittee sees as best practices?

      I think the closest to an actual answer you will find are the cpp core guidelines.
