+A destructor (either user-defined or compiler-generated) is implicitly declared `noexcept` (independently of what code is in its body) if all of the members of its class have `noexcept` destructors. By explicitly marking destructors `noexcept`, an author guards against the destructor becoming implicitly `noexcept(false)` through the addition or modification of a class member.
