Sorry, I was replying from my phone and missed a word. That's **not**
guaranteed for other library implementations.

(It's not formally guaranteed for libstdc++ either, but in practice
nearly every libstdc++ header includes <type_traits> because nearly
every header needs part of it, and that's unlikely to change).
