About @Parcelize.
If I understood correctly, Kotlin compiler can implement Parcelable in existing class.
But what about parcelable wrapper, e. g. class ParcelSomething(val something: Something) : Parcelable {..., where Something is not parcelable itself?

There is something for a CustomParceler annotation in the KEEP, but it doesn't look like it's been implemented [yet]: https://github.com/Kotlin/KEEP/blob/master/proposals/extensions/android-parcelable.md#per-property-and-per-type-parcelers

'Custom' means 'hand-written', isn't it?

[damian]

What would the alternative to hand-written be?
EDIT: Oh I see what you mean. No, the compiler can't implement Parcelable on arbitrary existing classes. It can only do so for your own classes annotated with @Parcelize.

Also, you could implement a Parceler in your companion object if you only need to parcel the whole class and not define them generally on a per-type basis: https://github.com/Kotlin/KEEP/blob/master/proposals/extensions/android-parcelable.md#custom-parcelables
