Kotlin vararg arguments method invoke jave vararg arguments method boxed two times

Vararg don't take an array?

If I have: fun sum(vararg numbers : Double) = numbers.sum() I can only call: sum(1,2,3) I can’t call: sum(arrayOf(1,2,3)) Why not?? In C# if I have: int sum(params int list) I can pass: sum(1,2,3) or sum(new int{1,2,3})

Use spread operator.
