Reflection - Compile-Time Introspection of C++

Explore compile-time introspection in C++ through this comprehensive ACCU 2021 conference talk. Delve into the core concepts of reflection and reification, examining various methods of language support, including the current Reflection TS approach and alternative considerations. Learn how reflection can enhance traditional generic programming techniques to develop more general algorithms based on class property introspection. Discover the potential of static reflection as a powerful upcoming feature for C++23, supported by advanced constexpr capabilities. Gain insights from examples demonstrating reflection's application in augmenting generic programming and creating versatile algorithms. Understand the implementation of reflection operators, types, and libraries, along with practical applications such as generating indirection, creating iterative pointers, and developing serialization algorithms.
