      // is the case here.  It would be much better to create a data
      // member of type "std::function<int(int)>" that is initialized
      // in the c'tor.  However, to demonstrate that a tool CAN be
      // constructed within a function call, we leave it as is.  See
      // the c'tor of AddIntsProducer for an example of better code
      // practice.
