I've never understood why this kind of syntax is a good idea.  program_options
uses it and I think it just confuses new users.

What's the advantage over individual function calls as Phil and others have
suggested?

I'm not passing judgement on the streaming-like interface.  Just wondering why
"overloading operator.()" is good for anything.
