The warning on the code below isn't useful since the formal argument of foo()
named i cannot be referenced in the body of the local struct. I.e., there is
no potential for referring to it by mistake since doing so would be a hard
error.
$ cat t.cpp && g++ -c -Wshadow t.cpp
int foo (int i)
{
struct {
int bar (int i) { return i; }
} s;
return s.bar (i);
};
t.cpp: In member function int foo(int)::<anonymous struct>::bar(int):
t.cpp:4: warning: declaration of int i shadows a parameter
t.cpp:1: warning: shadowed declaration is here
