Although this makes sense for classes, I'm not sure it does for  
namespaces:

namespace foo __attribute__((visibility("hidden"))) {
   void foo();
   void bar() __attribute__((visibility("default")));
}

This seems reasonable to me; the attribute on the namespace is  
setting a default, which is overridden on bar().
