  22 * SUMMARY:  Testing binding of function names
  23 *
  24 * Brendan:
  25 *
  26 * "... the question is, does Rhino bind 'sum' in the global object
  27 * for the following test? If it does, it's buggy.
  28 *
  29 *   var f = function sum(){};
  30 *   print(sum);  // should fail with 'sum is not defined' "
  31 *
