delete and splice behave differently in certain cases; the preferred methods are to use splice, shift, and pop. Using delete on an any element, other than the end, returns that element to an uninitialized state; it's undef if you examine it, and exists returns false for that element. On the other hand, using splice on that same element will remove it entirely from the array, thus shrinking the array's size. See perldoc -f delete.
