   v1.push_back( 2 );
   if ( v1.size( ) != 0 )
      cout << "New last element: " << v1.back( ) << endl;

// move initialize a vector of vectors by moving v1
   vector < vector <int> > vv1;

   vv1.push_back( move( v1 ) );
   if ( vv1.size( ) != 0 && vv1[0].size( ) != 0 )
      cout << "Newer last element: " << vv1[0].back( ) << endl;
