Consider:
void f();
namespace N { using ::f; }
void h()
{
void (& a)() = f; // ok
void (& b)() = N::f;
// error: invalid initialization of non-const reference of
// type ‘void (&)()’ from a temporary of type ‘void ()()’
}
Since in h, f and N::f are simply two ways of naming the same function, the
error seems unwarranted to me.
Comeau 4.3.9 accepts the code.
