Actually, I realized after I replied that he's talking about the *requirements* of the base container. That is, `std::stack::emplace` is supposed to call `emplace_back` on the container, right? But the requirements on the `std::stack` container doesn't say that `emplace_back` is *required*. And you can't call functions on something that you didn't require to actually have those functions.
