C++でC#のasみたいな書き方する遊び(糞)

template<class T>
struct as_op
{};

template<class T>
constexpr as_op<T> as_obj{};

template<class T, class U>
auto operator | (T* ptr, const as_op<U>& op) {
    return dynamic_cast<U*>(ptr);
}
#define as | as_obj

struct Super{virtual ~Super()=default;};
struct A : Super{
};
int main()
{
    Super* super = new A{};
    
    auto a = super as<A>;
    
    delete super;
}
