Introduction to object-oriented programming for those who have never done it before
summary
Claims that classic OO is actually class-oriented and that DCI (Data, Context, Interaction) restores Alan Kay’s original object model, with use cases implemented as runtime contexts that inject roles into domain objects. Shows concrete code (a transfer-money context where roles are injected and local getters do primitive work), points to a new trygve language implementation, and cites a controlled experiment at RIT reporting statistically significant higher comprehension and reduced context-switching for DCI versus class‑oriented Java.
