I don't understand. How would struct or class initialization be any different from simply doing, say, `for (auto& a : { x, y, z }) frob (a);` which is perfectly legal?

I didn't mention. I think the thought was with designated initializers the order of initialization is what? The order of the elements of the struct? Or the order where it's initialized. In C probably matters little as side effects are usually blatant. C++ I think cryptic side effects are common.
