Hi Rich, Thank you so much for your reply. But I am still confused about the "overload". As far as I understand, the functionalities provided by pargs class seems to be the subset of the ones provided by args class. So why cannot we let the client use args class to write the arguments? And I think it can also use args class to overload functions.
