Object-oriented programming in Lisp

Object-oriented programming (OOP) in Lisp involves organizing code around "objects," which are like self-contained entities containing data (attributes) and behavior (methods). Think of objects as real-world items with properties and actions—like a "Car" object with attributes like color and speed, and methods such as drive or stop. Lisp implements OOP through systems such as CLOS (Common Lisp Object System), allowing programmers to define classes (blueprints for objects), create instances, and customize behavior via inheritance. This approach promotes modular, reusable, and flexible code, making it easier to model complex systems by mirroring real-world relationships.
