No, Bradley wants the generator-iterator (what ES6 draft calls a Generator), not the generator function (GeneratorFunction). Any .callee would have to be a function, so a GeneratorFunction.

But the gist'ed example won't work:

  function*  doLogin_()  {
    try  {
      /* START ASYNC TRANSPILE */
      login(req).then(function  (session)  {
        gen.next(session);


You can't next an active generator.

Instead, the trick is to avoid promises inside the generator function. Put them "on the outside" (and "backstage") as task.js does. http://taskjs.org/.
