Leveraging Spl in the right way is crucial to avoid compromising the design of an application and taking advantage of the most portable php library at the same time. A wide use of the basic language structures is often the sign of a missing concept in the domain model. Passing around arrays and Iterators may be harmful if the implicit objects they represent do not fit with the operations available on them. We may have collections where elements can be removed, or repeated, in spite of business rules; queues and stacks that allow random access to all their elements, and so on.
