You should realize that what you're asking about is not OO, but 
programming by extension. Because "OO" became a synonym for "good", and 
early examples of OO were shown in languages that supported (or 
required) programming by extension, programming by extension got called 
OOP, but that is a misnomer.

Programming by extension does not necessarily have anything to do with 
object orientation. Programming by extension is an implementation 
technique. Object orientation is a design attribute and may be 
implemented without using programming by extension.
