I would really recommend a new system, you could do something like

public function onCheckArray(arr) {
  for (temp.i: getstringkeys("this.")) {
    if ((@ this.(@ temp.i)) == (@ temp.arr)) return true;
    if (temp.arr.size() == this.(@ temp.i).size()) {
      temp.check = 0;
      for (temp.f: temp.arr) {
        if (temp.f in this.(@ temp.i)) temp.check++;
      }
      if (temp.check == temp.arr.size()) return true;
    } 
  }
  return false;
}
