OK the coming compile time reflection features coming with C++26 are definitely mind blowing. It really opens the door toward a very different evolutionary path for C++. Many things can be done from libraries now and producing bindings to other languages shall become much simpler to.

Now it's once again about adding more to the language... This makes the question of how to extract a safer and leaner subset even more important. It's also asking for more tooling to support it, like the constexpr debugger mentioned during the questions.
