在VS2013中输入特征

Question

int main()
{
  struct C {
    C(const C&) = delete;
    C& operator= (const C&) = delete;

    C(C&&) {}
    C& operator=(C&&) { return *this; }
  };
  static_assert(std::is_copy_constructible<C>::value &&
                    std::is_copy_constructible<C>::value,
                "");
}

Why above code can be successfully compiled in VS2013?
