Static reflection is a forthcoming feature in the C++ programming that promises powerful new features for compile-time introspection of user source code. This feature, supported by increasingly capable constexpr facilities, will potentially be the Next Big Thing for C++23. This talk will cover the core concepts of reflection and reification and discuss several methods of providing language support for those features, including the approach taken by current Reflection TS and alternative approaches that are currently being considered. The remainder of the talk will present examples of how reflection can be used to augment traditional generic programming techniques to develop even more general algorithms based on introspection of class properties.
