The code on this page grew out of a discussion on the Object Technology in Computer Science Education list server. The discussion had been going on for about 36 hours in late March and early April 2000 centered on the question of "What is OO really; is it a real paradigm, different from procedural programming or is it just a packaging mechanism for procedural programming?" Both of the authors believe that it is a real paradigm shift, requiring a change in mental model in the practitioners.

The appearance of iterators in an object-oriented language appears to be inversely related to the power of the language's intrinsic control structures. Iterator classes are used for the sole purpose of enumerating the elements of an abstract collection class without revealing its implementation. We find that the availability of higher-order functions and function closures eliminates the need for these ad hoc iterator classes, in addition to providing the other benefits of "mostly functional programming".

An extensive discussion of subtyping, insidious problems with subclassing, and practical rules to avoid them.
