Is "this" accessible in SAMs?

By the way, while “this” does not work in a SAM, it does work in your original code:

val handler = Handler()
val runnableCode = object : Runnable {
    override fun run() {
        // do something
        handler.postDelayed(this, 2000)
    }
}
handler.post(runnableCode)
