Status of Annotations on typealias - supported?

Language Design

That’s great news – thanks!!

I’m unclear how to access them.

In the given example:

@DataAttribute("http://foaf/FirstName")
typealias FirstName = String
@DataAttribute("http://foaf/LastName")
typealias LastName = String

@Retention(AnnotationRetention.RUNTIME)
@Target(AnnotationTarget.TYPEALIAS)
annotation class DataAttribute(val value:String)

data class Person(val firstName: FirstName, val lastName: LastName)

How are the annotations associated with FirstName and LastName accessed via reflection?
