TIL: C++23 you can use named universal character escapes

#include <print>
int main() {
std::print("\N{GREEN HEART}"); // 💚
}

May I make you aware of the phantastic @compiler_explorer, that totally indispensable tool to every software developer - the brainchild of @mattgodbolt ?

I can speak only as an average C++ developer who works at a small company, and who happens to be stranded in the C++ committee.

For my own experiments, I have a personal bookmark in my browser called "C++23 playground" as a starting point for for more elaborate adventures in the C++ lands. May be, it helps you as well:

To the best of my knowledge, the provided flags will give you some highly recommended defaults for compiler diagnostics and maximum language conformance, in the three major implementations Clang/libc++, GCC/libstdc++, and MSVC/MS-STL. Maybe you'll get some inspiration for your daily grind.

Please support Matt and the entire CE team 🤘, f.e. by getting some swag that we nerds can proudly present in the public and wear as protective gear ☺️

Are you using std::ranges in your C++ code? If not, what is stopping you?

Ranges introduced a huge paradigm shift in the way we can write our C++ code. They can make the code way shorter, way better separated, and what's best - way more resilient to both logical and memory-related bugs. 🐞

If you haven't yet dabbled in ranges yourself, I've prepared a kind of cheatsheet reference article exploring many everyday use cases and how they can be improved by using the std::ranges library. 📏

You can read the article for free on my Medium:

Released v1.0.0 of bit-lite.

It now supports C++23 byteswap().

A somewhat less frivolous message than in the blue skies :)

Can somebody explain to me, why the last static assert fails? The value type has <=> operator returning strong ordering and std::map is clearly capable of having strong-ordered <=> operator.
