struct Base
{
virtual void f() = 0;

struct Derived : public Base
{
void f() final; // overrides Base::f
};
static_assert(!std::meta::is_final(^^Base::f));
static_assert(!std::meta::is_final(^^Base));
static_assert(std::meta::is_final(^^Derived::f));
static_assert(!std::meta::is_final(^^Derived));
struct final_class final {};
static_assert(std::meta::is_final(^^final_class));
