Lisp Notes - 1
The nearest thing Common Lisp has to a motto is the koan-like description, "the programmable programming language." While cryptic,that description gets at the root of the biggest advantage Common Lisp still has over other languages.
Ideas first introduced in Lisp include the if/then/else construct,recursive function calls, dynamic memory allocation, garbage collection,first-class functions, lexical closures, interactive programming, incremental compilation and dynamic typing.
