Hi. I have an interface `Iface` which is extended by a number of data classes (since you can't have an `open data class`). The interface is used in another class `data class Dclass&lt;out T : Iface&gt;(val ds: List&lt;T&gt;)`. I have Jackson deserializing some JSON into a `Dclass` instance. Can I do any better than using `@JsonTypeInfo` and `@JsonSubTypes` on the interface? I don't like having my superclasses knowing about their subclasses, even if it's just annotations. Yes, I am using the Kotlin extensions to Jackson.
