As you know. there is no ambiguity, no warnings needed. (The parameter is part of the identifier of the function)
Imo, this request falls into the category “do as I think, not as I say”. That is a discussion without end. Personally I am against ANY warnings of this kind. The reason is that I want my code to compile warnings free (default compiler behaviour) and I do not want an extra pragma in the code to instruct the compiler that when I am calling “foo()” I do indeed want to call “foo()”.
