=head1 SYNOPSIS

	use v5.10;
	use Tie::Cycle;

	tie my $cycle, 'Tie::Cycle', [ qw( FFFFFF 000000 FFFF00 ) ];

	say $cycle; # FFFFFF

=head1 DESCRIPTION

You use C<Tie::Cycle> to go through a list over and over again.
Once you get to the end of the list, you go back to the beginning.
You don't have to worry about any of this since the magic of
tie does that for you.
