I want a map between Int and any class. In Java it would be Map<Class<?>, Integer>. What's the Kotlin equivalent of that?

KClass等于Kotlin 的java.lang.Class.
An instance of KClass can be obtained with ::class on either a type or a value (i.e. String::class, 3.8::class).
如果需要KClass中的Java Class实例，可以使用java extension property:
val kotlinClass: KClass<String> = String::class
val javaClass: Class<String> = String::class.java
请记住，如果要使用Kotlin-Reflect的full features，则类路径上需要kotlin-reflect.
所以在你的例子中，类似功能是Map<KClass<*>, Int>.
