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...
