[Tristan Caron]

Hello, I'm not sure if it's a bug or I'm doing it wrong. I'm trying to use .copy() provided by data class, but the result is not really what I want.

data class Person(val name: String = "Tristan") {
    var age: Int = 1
}

fun main(args: Array<String>) {
    val person = Person()
    person.age = 3
    val personCloned = person.copy()
    println(personCloned.age) // It prints 1 and I was expecting 3
}

Can you give me some lights on it? Thank you.
