Destructuring in when

[Wasabi375]

How can compiler deal with classes like

class MixedPair constructor(x1  : String, x2 : String) {
    val x = x1 + x2
}

or is it reserved to data class ?

Destructuring in kotlin is done using the componentN functions marked with the operator keyword. You can define them for any class starting with component1. Data classes automatically generate them.
