Use Interface instead of enum for UserStatus

[hosni]

Hello
I'm trying to implement a package that depends on laravel-aaa.
But, I faced a problem, My User model's status is different than the dnj\AAA\Contracts\UserStatus that defined as contract.
As you know, we can not extend an Enum: Why enums aren't extendable
But, luckily Enums can implement Interface
So I suggest to define an Interface that named dnj\AAA\Contracts\IUserStatus and use this Interface as our input-output type and the UserStatus implements this Interface, see:

namespace dnj\AAA\Contracts;

enum UserStatus: string implements IUserStatus
{
    case ACTIVE = 'ACTIVE';
    case SUSPEND = 'SUSPEND';
}
