  /*
   * Brendan:
   *
   * Note that only callee and length can be overridden, so deleting an indexed
   * property and asking for it again causes it to be recreated by args_resolve:
   *
   * function g(){delete arguments[0]; return arguments[0]}
   * g(42)     // should this print 42?
   *
   * I'm not positive this violates ECMA, which allows in chapter 16 for extensions
   * including properties (does it allow for magically reappearing properties?).  The
   * delete operator successfully deletes arguments[0] and results in true, but that
   * is not distinguishable from the case where arguments[0] was delegated to
   * Arguments.prototype[0], which was how the bad old code worked.
   *
   * I'll ponder this last detail...
   *
   * UPDATE: Per ECMA-262, delete on an arguments[i] should succeed
   * and remove that property from the arguments object, leaving any get
   * of it after the delete to evaluate to undefined.
