You can have a wrapper function (not coroutine) that returns std::generator.

std::generator<T> wrapper(ReferenceType x) {
  return [](ValueType x)->std::generator<T>{
    /*implement coroutine*/
  }(DeepCopy(x));
}

DeepCopy(x) is evaluated before the initial suspend and its result lives on the coroutine frame.
