" summary

Claims that an object is just a function and demonstrates it concretely in Swift by implementing sets and lists as closures that capture instance values, selectors as enums then as strings, and a runtime message send that maps selector to method implementation. Builds constructors, unions and list count/at methods, explains type-tagging for signatures, invokes Graham's number as a scale joke, and completes a working object model in about 18 minutes.
