Multi-delegation/proxy class support

Language Design

It seems as tho there are multiple different ways that this could be implemented that all conflict with one another. One way to make this easier tho would be by having a class that implements that interface and takes a list of objects of that interface and then does the delegation (let’s call it SuperWrapper. Then, in you actual classes, you can just have a constructor parameter or a property which is a list of those interfaces, and then just delegate the interface to the SuperWrapper. Something kinda like this:

interface Test {
    fun doStuff1(arg1: Int, arg2 : String) 
    fun doStuff2(arg1: Any) : String 
}
class TestSuperWrapper(val tests: List<Test>){
    fun doStuff1(arg1: Int, arg2: String){
        tests.forEach { it.doStuff1(arg1, arg2)}
    }
    fun doStuff2 (arg1: Any) : String{
        return tests.map { it.doStuff2(arg1) }.join(",")
    }
}
class MyClass(tests: List<Tests>) : Test by TestSuperWrapper(tests) {
    // Other stuff
}
