value class with computed property. value classes may not have generic type parameters. nor can they have more than one "backed" property. If Bar is treated as an integer value at compile time, then how does it hold on to a reference to the computed property? Or better yet, how does a primitive value have a reference to the computed property?

Bar.kt

@JvmInline
value class Bar(private val _foo: Int){
    val computed: Int
        get() = _foo.toString().length
}

@Throws(AssertionError::class)
fun testBar(){
    val arg = 22
    val argLength = arg.toString().length
    val bar = Bar(arg)
    val length = bar.computed
    assert(length == argLength)
    assert(length > 0)
}
