Use List::Rotation::Cycle to loop through a list of values. Once you get to
|
|
the end of the list, you go back to the beginning.
|
|
|
|
List::Rotation::Cycle is implemented as a Singleton Pattern. You always just
|
|
get 1 (the very same) Cycle object even if you use the new method several
|
|
times. This is done by using Memoize on the new method. It returns the same
|
|
object for every use of new that comes with the same List of parameters.
