Do you want to just have a `str`? Or just a `dict`? Or a database class model instance directly? It all works the same way.

You actually don't have users that log in to your application but robots, bots, or other systems, that have just an access token? Again, it all works the same.

    return construct(e1, e2, e3, e4, e5, e6, e7, e8, e9, e10, e11);
  }

  // These go up to eleven. After that, you just get the varargs form, and
  // whatever warnings might come along with it. :(

This release shouldn't affect apps using FastAPI in any way. You don't even have to upgrade to this version yet. It's just a checkpoint. 🤓
