CMUCL is a free Common Lisp implementation, originally developed at Carnegie Mellon University. It compiles to native code as well as compact byte code; the compiler ("Python", not to be confused with the Python programming language) generates some of the fastest object code of any Common Lisp implementation.Fact|date=April 2008 CMUCL runs on most Unix-like platforms, including Linux and BSD; there is an experimental Windows port as well. Steel Bank Common Lisp is derived from CMUCL.

Features

* A sophisticated native-code compiler which is capable of powerful type inferences, and generates code competitive in speed with C compilers.Fact|date=April 2008
* Generational garbage collection and multiprocessing capability on the x86 ports.
* A foreign function interface which allows interfacing with C code and system libraries, including shared libraries on most platforms, and direct access to Unix system calls.
* Support for interprocess communication and remote procedure calls.
* An implementation of CLOS, the Common Lisp Object System, which includes multimethods and a metaobject protocol.
* A graphical source-level debugger using a Motif interface, and a code profiler.
* An interface to the X11 Window System (CLX), and a sophisticated graphical widget library (Garnet).
* Programmer-extensible input and output streams.
* An Emacs-like editor implemented in Common Lisp.
