I have my own map type: ```interface EnumMap<K : Enum<K>, out V> : Map<K, V> { ...

# serialization

I have my own map type:

interface EnumMap<K : Enum<K>, out V> : Map<K, V> {
    override operator fun get(key: K): V
}

interface MutableEnumMap<K : Enum<K>, V> : EnumMap<K, V> {
    operator fun set(key: K, value: V)
}

and its corresponding implementation:

@Serializable
class MutableEnumMapImpl<K : Enum<K>, V> : MutableEnumMap<K, V> {
    // ...
}

I also have a custom KSerializer for the base EnumMap type that basically mimics the built-in map serializer with some additional logic, but I can't figure out how to register it in my SerializersModule so when it sees a MutableEnumMapImpl it serializes it using it

class EnumMapSerializer<K : Enum<K>, V>(
    private val keySerializer: KSerializer<K>,
    private val valueSerializer: KSerializer<V>,
) : KSerializer<EnumMap<K, V>> {
    // ...
}

Any help would be greatly appreciated!

I have managed to do this by changing my interfaces to be abstract classes and setting @Serializable(EnumMapSetializer::class) to the EnumMap abstract class, and it seems to work, but I would like to keep these as interfaces if possible.
