All requested features delivered. Speculation avoided. Mindful of our tendency toward completeness, necessary code is added, unnecessary code is removed. Refactored.
Implementations incomplete - shadows of the their real-world counterparts, yet precisely the functions and properties required. The desire to add more, tempered by the satisfaction of not doing so.
Technique and knowledge are increased to decrease their application.
