SetRequired should return the original class type, plus the required keys
I don't really know if this is possible, but here's what I have
PaymentEntity is a class
type CardPaymentEntity = SetRequired<PaymentEntity, 'processor'>;
static fromPayment(payment: CardPaymentEntity, opt: FromPayment): PaymentAuthorizationEntity {
return new PaymentAuthorizationEntity(
payment.amount,
payment.currency,
payment, // compile error here, because CardPaymentEntity is not a PaymentEntity class
Argument of type '{ readonly status: PaymentStatus; readonly amount: number; readonly currency: Currency; readonly orderId: string; readonly methodType: PaymentMethodType; ... 8 more ...; readonly processor: Processor | null; }' is not assignable to parameter of type 'PaymentEntity'.
