I would like to rename this to [[object theory]]. I understand object-oriented programming is the most common term and nearly no one uses a word like object theory instead of it. But the trouble with the current title is OOP is a POV'd term. The situation is similar to that in socialism or communism. The majority of people claim class, inheritance and encapslation are foundamental aspects of OOP but some argue inheritance is not always necessary, for instance. It doesn't matter who is right. The fact is there are disputes regarding the definition of object-oriented programming. So it would be troublesome with the current name as some claim inheritance is an aspect of class-based OOP then the article sholdn't cover, while some say inheritance is a foundamental of OOP and there is no reason that the article doesn't cover it. I don't think such debate would be settled. The benefit of the title [[object theory]] is it is more abstract term. It can discuss languages before object-oriented programming. Ada8 something supports objects but is usually considered not OOP. Then where we should discuss such? A separate article? The title object theory implies it is about programming aspect regarding objects. It is a broader term that can contain class-based OOP, object-based programming and so on. [[Subprogram]] is an good example. People hardly uses a term subprogram over subroutines or functions. But in encyclopedia, use of such an abstract term is preferable because if the article named function, it implies a subprogram should be a function like in math, which is not the case. If named subroutine, it tends to emphasizes a behavior as side-effect and it makes hard to talk about function in functional languages. OOP is a similar case.

Common Lisp is NOT a object oriented language.You can do object oriented programming in Common Lisp (it even has its own set of operators for that: the Common Lisp Object System. Or you can write your own), but you don't have to, and most of the time, you won't need the extra garbage.

If you want a separate article called [[object theory]] that explains differnet methods of using objects in programming languages then fine. But the aspects of the OO paradigm discussed in this article (abstraction, encapsulation, polymorphism and inheritance) is a vast subject that deserves a least a whole page devoted to it. What you have us call it? OOP is the universally understood term used for these concepts. [[User:Mintguy|Mintguy]] 14:01 23 May 2003 (UTC)


:I'm a bit confused. The argument I see here is that because one can avoid doing object oriented programming in Common Lisp, Common Lisp is not object oriented. But that applies to many languages, e.g. C++ can be used procedurally (in its C subset). There is a term in the article "pure OO languages" which is defined as languages where everything is treated consistently as an object, which clearly Common Lisp and C++ do not satisfy. But the general concepts of OO seem present in CLOS. [[User:Mathnerd314159|Mathnerd314159]] ([[User talk:Mathnerd314159|talk]]) 01:18, 16 February 2024 (UTC)
:Please don't use the current content as an excuse. I want to rename first because otherwise, people will claim it is not OOP. Certainly we want to discuss what is OOP? But the more important is, history of OOP, point of views, variants, and so on. They are certainly beyond an article named object-oriented programming. Again, oftentimes, broader term serves well in encyclopedia. I showed an example above. -- [[User:TakuyaMurata|Taku]] 15:11 23 May 2003 (UTC)

:But all values in Common Lisp are objects and instances of some class. See for example the [https://www.lispworks.com/documentation/HyperSpec/Body/t_intege.htm integer class]. You do not have to write your own classes, still, and you can use normal functions instead of generic functions. But all classes (including structure classes made by defstruct) can be dispatched on by generic functions. I find using classes and generic functions in Common Lisp is useful and not garbage, and certainly people do use those features of CLOS, but "the extra garbage" would not be starting that discussion on the right foot.
