 /* GCC's -Wshadow triggers at scenarios like this: 
 *
 *   struct foo{};
 *   template<typename Base>
 *   struct derived:Base
 *   {
 *     void f(){int foo;}
 *   };
 * 
 *   derived<foo>x;
 *   x.f(); // declaration of "foo" in derived::f shadows base type "foo"
 *
 * This makes shadowing warnings unavoidable in general when a class template
 * derives from user-provided classes, as is the case with foa::table_core
 * deriving from empty_value.
