Handling Variable-Length Iterables with Fill Values

This function utilizes `itertools` and `collections` modules' `zip_longest` and `deque` functionalities to handle iterables of different lengths and fill the shorter sequences with a specified fill value.

        for d in deques:
            d.append(fillvalue)
