Keep yaml as-is for property when deserializing

[gwidion]

When I break down my use case into a minimal example, I'd like to deserialize a yaml similar to this:

name: Peter
values:
  key: val
  key2:
    - val2

into a class that has some properties and one of them should contain the yaml without an explicit structure. This would be ideal

@Serializable
data class Person(
  val name: String,
  val values: Map<String, Any>
)

but such map cannot be used for serialization because of Any type. I was thinking if YamlNode (or something else used internally by kaml) could be used but it isn't serializable either. Could you help me if there's a way to achieve that?
