    Wouldn’t compilers be able to optimize runtime things out? I know that GCC does so for some basic RTTI things, when types are known at compile time.

      For runtime reflection, no, you’d specifically be able to do things that would be impossible to optimize out.

      But the proposal is actually for static (i.e. compile-time) reflection anyway, so the original performance claim is wrong.

        Yeah, that’s what I was thinking of. I don’t know how C++ could reasonably have Java-like reflections anyway…
