How to pass a type to generic method in Kotlin?

Here’s a complete example:

import kotlin.reflect.KClass

data class User(val name: String)
data class Student(val name: String)

fun getUsers(): List<User> = listOf(User("JB"))
fun getStudents(): List<Student> = listOf(Student("Claire"))

fun <T: Any> getData(clazz: KClass<T>): List<T>? {
    return when(clazz) {
        User::class -> getUsers() as List<T>
        Student::class -> getStudents()  as List<T>
        else -> null
    }
}

fun main(args: Array<String>) {
    val types = listOf(User::class, Student::class)
    types.forEach { type ->
        val data = getData(type)
        println(data)
    }
}
