class_docstr: Plugin to convert XComArg to the runtime type.
  
  This allows us to pass an *XComArg* to a downstream task, such as::
  
      @task
      def f(a: str) -> int:
          return len(a)
  
  
      f(op.output)  # "op" is an operator instance.
      f(g())  # "g" is a taskflow task.
  
  where the *a* argument of ``f`` should accept a *str* at runtime, but can be
  provided with an *XComArg* in the DAG.
  
  In the long run, it is probably a good idea to make *XComArg* a generic that
  carries information about the task's return type, and build the entire XCom
  mechanism into the type checker. But Python's type system is still limiting
  in this regard now, and (using the above example) we yet to have a good way
  to convert ``f``'s argument list from ``[str]`` to ``[XComArg[str] | str]``.
  Perhaps *ParamSpec* will be extended enough one day to accommodate this.
