XLISP is: a family of Lisp implementations written by David Betz and first released in 1983.

The first version was a Lisp with object-oriented extensions for computers with limited power. The second version (XLISP 2.0) moved toward Common Lisp, but was by no means a complete implementation. After a long period of inactivity, the: author released a new version based on XSCHEME, his Scheme implementation. The most current version follows the——Scheme R3RS standard.
