The C++ reflection improves a lot in C++20, but it's still very limited compared to that aspect of Nim, or even Zig. The std::meta::info and "splices" based on Haskell for C++26 are incredibly exciting to me. I have many use cases in mind. Splices in combination with std::embed will make C++ basically just a bad Racket (but one with inline assembly!).
