Proposal to add zipWithNull (as seen on #advent-of-code)

fun <T, R> Iterable<T>.zipWithNull(other: Iterable<R>): List<Pair<T?, R?>> = buildList {
  val first = [e-mail]()
  val second = other.iterator()
  while (first.hasNext() || second.hasNext()) {
    val left = if (first.hasNext()) first.next() else null
    val right = if (second.hasNext()) second.next() else null
    add(left to right)
  }
}

There has been a proposal for a more universal function like this for a long time. zipAll as know from some other languages.
