Purge data class

Support
1

Is there a method to purge (clean to default values) of a data class instead of recreating it? Like

val cache = Cache()
cache.purge()

data class Cache(
  val list1: MutableList<Int> = mutableListOf()
  val list2: MutableList<Int> = mutableListOf()
)

It’s a minor case and there can be troubles with non-default values but maybe it can be useful. Other way is to make a nested class like:

class CachePurgeable{
    var cache = Cache()
        private set
    fun purge() {
         cache = Cache()
    }
}

That seems to intrinsically defeat the purpose of data classes
