It would seem strange that they would want to illustrate it as a point.
 In my opinion, the ability to use different parameter names is a flaw,
not a feature - I can't think of any conceivable use for it.  (I can
accept that it is a convenience to compiler writers that don't have to
check the names, and that it is a convenience to programmers who don't
have functions declared in headers properly.)
