How do I see if a class has an init block using reflection?

If I have a Kotlin class like the following:

data class Foo(
    val count: AtomicInteger
) {
    init {
        count.incrementAndGet()
    }
}

How do I determine that this class has an init block using reflection?

The init block does not appear in Foo::class.members and I can't see a way of determining it from Foo::class.constructors.

Is there any way to find out information about the init block using kotlin.reflect?

This information is not available after compilation.

Init blocks and property initializers on JVM are compiled into some mixture of constructors and/or field initializers. It’s up to the compiler how it wants to do this in an optimal way.
