Hi Phil, so you want metaprogramming facilities to autogenerate code. The current direction is to first get static Reflection integrated into the standard and build metaprogramming facilities from there. This is a huge topic and is planned to be finished 2029+++ Do you know those papers: P1240R2: Scalable reflection in C++ https://www.open-std.org/jtc1/sc22/wg21/docs/papers/2022/p1240r2.pdf P2320R0: The Syntax of Static Reflection https://www.open-std.org/jtc1/sc22/wg21/docs/papers/2021/p2320r0.pdf P2237R0: Metaprogramming https://www.open-std.org/jtc1/sc22/wg21/docs/papers/2020/p2237r0.pdf   If you have specific feedback for the current direction of reflection or involve yourself to help resolve all the issues and bring e.g. Static Reflection to C++26 and Metaprogramming to C++32, you should read deeper those and related papers and then write to the authors.   C++ will get a thought-out general solution for metaprogramming, not a quick-fix. This will take some time.   In the meantime, there are smartpointers in the standard library and external libraries, and code preprocessors and memory checkers, which bind themselves to a program or within the Standard Libraries.   Best, Sebastian PS There was a talk on Cppcon by Andrei Alexandrescu: Reflection in C++, where he talks about current and future generic programming. https://cppcon.digital-medium.co.uk/session/2022/reflection-in-c/ It currently probably is not available free of charge yet, but for an online conference pass.   -----Ursprüngliche Nachricht----- Von:Phil Bouchard <boost_at_[hidden]> Gesendet:Di 27.09.2022 18:21 Betreff:Re: [std-proposals] Rust vs C/C++ vs C++ Superset An:std-proposals_at_[hidden]; What I would like to integrate into the C++ standards first and foremost is a framework to allow implicit addition of class members, parameters, and scope instances, just like what the C++ Superset source-to-source compiler is doing right now.
