Hi guys, Im trying to cleanup this

class RetryWithDelay(val maxRetries: Int, var delay: Long) :
    Func1<Observable<out Throwable>, Observable<*>> {
  internal var retryCount = 0

  override fun call(attempts: Observable<out Throwable>): Observable<*> {
    return attempts.flatMap(Func1<kotlin.Throwable, rx.Observable<*>> { throwable ->
      if (++retryCount < maxRetries) {
        Observable.timer(delay, TimeUnit.SECONDS)
      } else {
        Observable.error<Throwable>(throwable)
      }
    })
  }
}

into

class RetryWithDelay(val maxRetries: Int, var delay: Long) :
    Func1<Observable<out Throwable>, Observable<*>> {
  internal var retryCount = 0

  override fun call(attempts: Observable<out Throwable>): Observable<*> {
    return attempts.flatMap({ throwable ->
      if (++retryCount < maxRetries) {
        Observable.timer(delay, TimeUnit.SECONDS)
      } else {
        Observable.error<Throwable>(throwable)
      }
    })
  }
}
