template <class T>
struct has_nothrow_destructor : public true_type-or-false_type {};
        Inherits: If T is a (possibly cv-qualified)
        type with a non-throwing destructor then inherits from true_type,
        otherwise inherits from false_type.
        Type T must be a complete
        type.
      
        Compiler Compatibility: Either requires
        C++11 noexcept and decltype or else some (unspecified) help from
        the compiler. You may test to see if the necessary support is available by
        checking to see if !defined(BOOST_NO_CXX11_DECLTYPE) && !defined(BOOST_NO_CXX11_NOEXCEPT) is true.
