  cases[4] = function() { foo++ };
  cases[5] = function() { foo++ };
  cases[6] = function() { foo++ };
  cases[7] = function() { foo++ };
  cases[8] = function() { foo++ };
  cases[9] = function() { foo++ };
  
  function hash(index) { cases[index](); }
  function switched(index) {
  switch (index) {
    case 0:
      cases[0](); break;
    case 1:
      cases[1](); break;
    case 2:
