Unused arguments when destructing an object in Kotlin

Question

When destructuring an object, is it possible to only declare the variables I need?

In this example I'm only using b and my IDE is giving me a warning that a is unused.

fun run() {
    fun makePair() = Pair("Apple", "Orange")

    val (a, b) = makePair()

    println("b = $b")
}

Answer 1

Since Kotlin 1.1, you can use an underscore to mark an unused component of a destructing declaration:

fun run() {
    fun makePair() = Pair("Apple", "Orange")

    val (_, b) = makePair()

    println("b = $b")
}

Answer 2

You could use:

val b = makePair().component2()
