I read code like this in c++:

const auto candidate_path = std::invoke([&]() {
  if (status == ModuleStatus::SUCCESS || status == ModuleStatus::FAILURE) {
    // clear candidate path if the module is finished
    return convertToPath(nullptr, false, planner_data);
  }
  return convertToPath(
    observer.lock()->getPathCandidate(), observer.lock()->isExecutionReady(), planner_data);
});

The code creates an anonymous function and capture everything by reference [&](){} and then it’s called by std::invoke(), I’d like to see if there is any benefit doing it?

Thanks.
