    # This function will return an iterator that aggregates elements from each of the iterables.
    # It will stop when the shortest iterable is exhausted, filling in missing values with fillvalue until all iterables are exhausted.
    from itertools import zip_longest as _zip_longest
    return _zip_longest(*iterables, fillvalue=fillvalue)
