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. -- Jeff Carter "If you think you got a nasty taunting this time, you ain't heard nothing yet!"
