This stems out of a conversation a friend and I just had that left us guessing the answer. I am sure someone here will be able to enlighten us.

He is using foreach on an array. We were wondering if the commands in the loop are carried out on each element of the array sequentially (by index) or at random, or some other way. From "Programming Perl" I remember that with foreach there is no way of knowing where in a list one is. This seems to allude to a non-sequential process. Is this true?
