Design pattern: Iterator
Description: "Provide a way to access the elements of an aggregate object sequentially without exposing its underlying representation."
This pattern can be used with both classes and prototypes.
A straightforward implementation of this design pattern is to define an iterator predicate that enumerates elements using backtracking. This predicate can then be called from meta-predicates such as the de facto standard forall/2 predicate.
