is there any reason as to why Job doesn't have a Failed state like Deferred? currently a Job that fails (e.g throws an unhandled exception) ends up in a Completed state. The only way to actually know if it was a failure is by checking the message of the CancellationException. Here is an example:

fun main(args: Array<String>) = runBlocking {
    val job = launch {
        throw TODO("Not ready!")
    }

    // wait for it to crash
    delay(200)

    println("cancelled [${job.isCancelled}]")   // -> false
    println("active [${job.isActive}]")         // -> false
    println("completed [${job.isCompleted}]")   // -> true
}
