 Scala requires a companion object to have the same name as its companion class, and it has to be in the same file. In Kotlin however it is required to be within the class and use the keywords `companion object`. Object name, in that case, is optional, which makes things a bit interesting. And finally, you can have only one companion object within your class.
 
 ```kotlin
-data class Items(val items: List<Int>) {
-
-    val emptyItems = empty()
-    val anotherEmptyItems = Builder.empty()
-
-    companion object Builder {
-        fun fromString(s: String): Items = Items(s.split(",").map { it.toInt() })
-        fun empty(): Items = Items(listOf())
-    }
