This is just off the top of my head, and could probably be shorter. This assumes that @array is a multiple of 4 elements, and drops anything that's modulo 4:
If you want to handle a remainder chunk specially, you can do so after the while exits... Edit: This is bad in that the modulo/lost elements are from the center of the list, not the end. Unless you are certain that you list is always a multiple of 4 in length, you'll definitely want to handle the remainder. --rjray
