How do I handle circular lists? Can't Post

(From the Perl FAQ)

How do I handle circular lists?

Circular lists could be handled in the traditional fashion with linked lists, or you could just do something like this with an array:

Code
    unshift(@array, pop(@array));  # the last shall be first 
push(@array, shift(@array)); # and vice versa
