You said:

So how does kotlinx achieve zero-cost compatibility with Java collections without having something like `.asKotlin` and `.asJava`? Because otherwise there is no difference between Scala and Kotlin in this regards.
- joshlemer 5y agobecause the persistentList/Collection/etc in kotlinx implement the appropriate java collection interfaces: import java.util.List; public class Foo { public static void blah(List<Integer> list) { } } Kotlin: import kotlinx.collections.immutable.persistentListOf fun main(): Unit { Foo.blah(persistentListOf(1,2,3)) } This compiles fine
