  dint A(1,2),B(3,4);
  cout << "hull(A,B)" << hull(A,B) << endl;
  cout << "hull(B,A)" << hull(B,A) << endl;
  cout << "hull(A,5)" << hull(A,Num(5)) << endl;
  cout << "hull(5,A)" << hull(Num(5),A) << endl;

  cout << "hull(5)" << hull(Num(5)) << endl;
  cout << "sym_hull(5)" << sym_hull(Num(5)) << endl;
