@useResult
List<T> interleave(Iterable<T> other) {

  final Iterator<T> iterB = other.iterator;
  final List<T> result = <T>[];
  while (true) {
    if (iterA.moveNext()) {
      result.add(iterA.current);
    } else {
      break;
    }
    if (iterB.moveNext()) {
      result.add(iterB.current);
    } else {
      break;
