// Proposal for polymorphic classes:
// object_ptr::as<Type> does the following checks;
//
// 1. The requested type has super class
// 2. Super class has discriminator column defined
// 3. Super class has discriminator value defined
// 4. Discriminator value is mapped to the requested type
//
// If all checks succeed, the requested is fetched from
// the database.
// schema.attach<jobs::Payload>("payloads", make_polymorph("type"));
// schema.attach<jobs::Payload, jobs::IdPayload>("id_list_payloads", make_polymorph_type("IdPayload"));
// schema.attach<jobs::Payload, jobs::IdListPayload>("id_payloads"make_polymorph_type("IdListPayload"));
// object::object_ptr<jobs::Payload> payload;
// auto result = payload.as<jobs::IdPayload>();
// if (result.is_ok()) {
// const auto& is_payload = result.value();
// // Use requested type
// id_payload->id = 1;
// }
// payload.is_polymorphic();
// payload.is_polymorphic_type<jobs::IdPayload>();
