[cfe-dev] -Wshadow rationale for data members

[Axel Naumann]

Hi,

struct A {
   static void* f; void* g;
   struct B { static void* f; void* g; };
};
struct C { static void* f; void* g;};
struct D: public C { static void* f; void* g; };

compiled with
clang++ -c -Wall -Wshadow -O2 t.cxx
generates the warning

t.cxx:3:28: warning: declaration shadows a static data member of 'A'
[-Wshadow]
   struct B { static void* f; void* g; };
                           ^
t.cxx:2:17: note: previous declaration is here
   static void* f; void* g;
                ^

What about non-static members? And why only for nested classes (B), not
for inheritance (D)? Shouldn't nested classes be allowed to re-define
static variables with the same name as an outer one?

Cheers, Axel.
