Object Lisp

Lisp is a family of computer programming languages with a long history and a distinctive, fully parenthesized prefix notation. Originally specified in 1958, Lisp is the second-oldest high-level programming language in widespread use today. Only Fortran is older, by one year. Lisp was invented by John McCarthy while he was at the Massachusetts Institute of Technology (MIT). McCarthy published its design in a paper in Communications of the ACM in 1960, entitled "Recursive Functions of Symbolic Expressions and Their Computation by Machine, Part I". He showed that with a few simple operators and a notation for functions, one can build a Turing-complete language for algorithms. Lisp has since gone through a number of major revisions, and dialects have diverged to a great extent. The most widely known general-purpose Lisp dialects are Common Lisp and Scheme. Lisp was originally created as a practical mathematical notation for computer programs, influenced by the notation of Alonzo Church's Lambda Calculus. It quickly became popular among researchers in academic circles, who used it as a tool for rapid prototyping and as a foundation for more sophisticated programming languages and systems. Lisp was originally envisioned as a portable, easily extensible language. It was also intended to provide a unified approach to symbolic computation, which would enable the programmer to manipulate symbols as well as numbers. Lisp has a number of features that make it attractive for a wide range of applications. These include: A powerful macro system that allows the programmer to extend the language. A rich set of data types, including strings, lists, and vectors. A wide range of control structures, including conditionals, iterators, and exceptions. A uniform syntax that makes it easy to parse and process Lisp programs. An interactive environment that allows programmers to experiment and debug programs quickly. Lisp is a versatile language that can be used for a wide variety of tasks, from simple scripts to complex applications. It is particularly well suited for tasks that require rapid prototyping, such as computer-aided design or artificial intelligence programs.
