    assertEquals(9, childrenP40.size());
    // then via property name
    List<SimpleNode> children = queenVictoria.out("child")
        .collect(Collectors.toCollection(ArrayList::new));
    assertEquals(9, children.size());
    if (debug) {
      children.forEach(child -> child.printNameValues(System.out));
