Macintosh Common Lisp for Mac

From Digitool:

Macintosh Common Lisp 5.0 (MCL 5.0) is a MacOSX native object-oriented dynamic language (OODL) from Digitool, Inc. It implements the ANSI standard for the Common Lisp programming language and CLOS, and is fully integrated with the Macintosh family of personal computers.
This release is a beta and its discounted price includes the final release expected in January 2003.
MCL is a completely integrated development environment, including a fast incremental compiler which produces efficient native PowerPC code, a window-based debugger, a source code stepper, a dynamic object inspector, a stack backtrace inspector, a programmable Macintosh-style emacs-like editor, online documentation, and an interactive interface toolkit.
MCL provides both high-level object-oriented user interface class library and complete low-level access to the Macintosh Toolbox. Using MCL, you can create a standalone double-clickable Macintosh application using less than 2MB of disk space which can be run with 2MB or more of memory.
The MCL 5 Single User License gives one person the right to use MCL for program development purposes. The current release includes MCL 5.0 beta for the MacOSX platform. When you purchase this product you get:
