}) async {
  Object? nextStepInput = input;

  for (final step in [first, ...middle]) {
    nextStepInput = await step.invoke(
      nextStepInput,
      options: step.getCompatibleOptions(options),
    );
  }

  return last.invoke(
    nextStepInput,
    options: last.getCompatibleOptions(options),
