 I'm not talking about the "unused argument" warning.
 Sorry if I was not clear.
 
 What I would like is a new warning that tells me that I'm hiding the data
 member's name with the member function's argument name.
 
 The updated code below shows a situation where I would like a warning
 (and SunPRO emits one) :
 
 struct A
 {
   int i;
   void f(int i) const;
 };
 
 void A::f(int i) const
 {
   (void) i; // I use i somehow, but did I meant A::i or the argument i ???
 }
