class ScoreCard(val base: Int) {
    fun total(bonus: Int): Int {
        return base + bonus
    }
}

fun main() {
    val bonus = 
    val card = ScoreCard(10)
    val total = with(card) {
        total(bonus)
    }

    println("bonus=$bonus")
    println("total=$total")
}

class ScoreCard(val base: Int) {
    fun total(bonus: Int): Int {
        return base + bonus
    }
}

fun main() {
    val bonus = 
    val card = ScoreCard(10)
    val total = with(card) {
        total(bonus)
    }

    println("bonus=$bonus")
    println("total=$total")
}

class ScoreCard(val base: Int) {
    fun total(bonus: Int): Int {
        return base + bonus
    }
}

fun main() {
    val bonus = 
    val card = ScoreCard(10)
    val total = with(card) {
        total(bonus)
    }

    println("bonus=$bonus")
    println("total=$total")
}

with `with` takes a receiver object and returns the block result.
