kotlin
data class CartSnapshot(
val id: String,
val accessToken: String,
val items: MutableList<String>,
) {
var revision: Int = 0
}
fun addItem(snapshot: CartSnapshot, item: String): CartSnapshot {
val next = snapshot.copy()
next.items += item
next.revision = snapshot.revision + 1
println("updated: $next")
return next
