declval is in use for exception specifications since at least 5.5 (in QPair). As for type_traits, please note that for many of them, there is no other way to get at the information (std::is_trivial*, std::is_polymorphic, even some std::is_nothrow_constructible, because a seemingly equivalent noexcep operator (say, noexcept(T(std::declval<T>()) also includes the dtor). I propose that whatever we decide here is checked for in machine-readable form in tst_compiler.
