Sun Microsystems Inc’s SunPro unit is handing its Common Lisp implementation over to Menlo Park, California-based Lucid Inc, already a leader in Common Lisp for Unix. Lucid will acquire exclusive rights to Sun Common Lisp, which will be renamed Lucid Common Lisp. The company is offering it immediately, but SunPro will continue to offer Sun Common Lisp until the end of the year, although its customers can receive support from Lucid immediately. In response to evolving market requirements, both partners agree that a single source supplier for the language will best meet the needs of the Lisp community, Lucid comments. Financial terms were not disclosed.
