Current Perl documentation can be found at perldoc.perl.org. Here is our local, out-dated (pre-5.6) version: Circular lists could be handled in the traditional fashion with linked lists, or you could just do something like this with an array:
unshift(@array, pop(@array)); # the last shall be first push(@array, shift(@array)); # and vice versa
