Kotlin Array/List extractor in Pattern Matching

Question

In Scala one can extract array elements in a pattern matching statement. For example, I want to take the first two elements of a string input:

  private def parseFieldSize(s: String): Option[(Int, Int)] =
    try {
      s.split(" ").map(_.toInt) match {
        case Array(x, y, _*) => Some(x, y)
        case _ => None
      }
    } catch {
      case _: NumberFormatException => None
    }

How do I do the same in Kotlin? The closest I can get is:

   private fun parseFieldSize(s: String): Pair<Int, Int>? =
      try {
        val inputInts = s.split(" ").map { it.toInt() }
        if (2 == inputInts.size)
          Pair(inputInts[0], inputInts[1])
        else
          null
      } catch (e: NumberFormatException) {
        null
      }
