Common Lisp the Language
PREFACE: X3J13 voted in January 1989 (LOOP-FACILITY) to adopt an extended definition of the loop macro as a part of the forthcoming draft Common Lisp standard.
This chapter presents the bulk of the Common Lisp Loop Facility proposal written by Jon L White. I have edited it only very lightly to conform to the overall style of this book and have inserted a small number of bracketed remarks identified by the initials GLS. (See the Acknowledgments to this second edition for acknowledgments to others who contributed to the Loop Facility proposal.)
