C++26 to Feature Compile-Time Reflection: Goodbye Boilerplate, Hello High Performance

Herb Sutter has announced that C++26 will include compile-time reflection, a game-changer for C++ development. Compile-time reflection provides access to a program's own structure, enabling tasks like enumerating a class's methods. This is particularly impactful for libraries like simdjson, allowing high-speed conversion between custom data structures and JSON strings without boilerplate code. The article demonstrates generating efficient SQL insert statements using compile-time reflection, reducing boilerplate and improving code reusability and safety. While the code might look complex, the performance gains and code simplification are significant.
