@dirksamson This compares two collections, including the ordering
$original = collect([1, 2, 3]);
$original->sort()->zip($original)->contains(fn(Collection $dates) => $dates->duplicates()->isEmpty()); // false
$original = collect([1, 3, 1]);
$original->sort()->zip($original)->contains(fn(Collection $dates) => $dates->duplicates()->isEmpty()); // true
