# serialization

[Jan Skrasek]

I want to utilize combined open and closed polymorphism, I have this class tree:

// in library
@Serializable
interface Base

// in user code
sealed interface All : Base {
   @Serializable
   object A : All

   @Serializable
   data class B(...) : All
}

Ideally, I'd like to register as a subclass only the All type and not every children (A, B, ...). Do I miss something or it is not possible?
