如何将kotlin.Pair与数据绑定一起使用？

data class Person(val name: String, val age: Int)

<TextView
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="@{person.name + ', ' + person.age}" />

val person = Person("John Doe", 30)
binding.person = person

val binding = DataBindingUtil.setContentView<ActivityMainBinding>(this, R.layout.activity_main)

val personData = Pair("John Doe", 30)
binding.personData = personData

<TextView
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="@{personData.first + ', ' + personData.second}" />
