   It does support self-reset, exactly as does the MSVC implementation   
   that Daniel Krugler said is non-conforming, because it doesn't   
   call get_deleter()(old_value) if the old value and the new value   
   are the same.   
      
   This is different than the reset() later in the same file, which is   
      
          void   
          reset(pointer __p = pointer()) noexcept   
          {   
            using std::swap;   
            swap(std::get<0>(_M_t), __p);   
            if (__p != nullptr)   
              get_deleter()(__p);   
          }   
      
   The difference is   
            if (__p != nullptr)   
   vs   
            if (__p != pointer())
