Quick question - does when perform == check or === check when comparing objects? It doesn’t mention on the docs

when (message) {
        removeMessage -> removeItem(subject)
        else -> sendItem(subject, message)
    }

companion object {
        val removeMessage = Message { mapOf<String, String>() }
    }

^^ Answered myself by converting to if

if (it.second == removeMessage) removeItem(subject)
                                else sendItem(subject, message)

if looks so much better.

this is a simple case with only 2 options..

You may answer your question yourself by compiling this code:

data class D(val v: Int)

when (D(2)) {
  D(2) -> println("Yes!")
  else -> println("No...")
}
