  // %          note 1: We can't copy privileged methods, as those require instantiation (with potential side-effects when called)
  // %          note 1: We've chosen not to assign to or create a prototype object on the destination object even if the original object had the methods on its prototype
  // *     example 1: var A = function () {};
  // *     example 1: A.prototype.method = function () {};
  // *     example 1: var b = {};
  // *     example 1: aggregate_methods_by_list(b, 'A', ['method'], false);
  // *     returns 1: undefined
