26 | |
27 | ;; These are extensions to Emacs Lisp that provide a degree of | |
28 | ;; Common Lisp compatibility, beyond what is already built-in | |
29 | ;; in Emacs Lisp. | |
30 | ;; | |
31 | ;; This package was written by Dave Gillespie; it is a complete | |
32 | ;; rewrite of Cesar Quiroz's original cl.el package of December 1986. | |
33 | ;; | |
fcd73769 RS |
34 | ;; Bug reports, comments, and suggestions are welcome! |
35 | ||
36 | ;; This file contains the portions of the Common Lisp extensions | |
37 | ;; package which should be autoloaded, but need only be present | |
38 | ;; if the compiler or interpreter is used---this file is not | |
39 | ;; necessary for executing compiled code. | |
40 | ||
41 | ;; See cl.el for Change Log. | |

7c1898a7 SM |
1904 | well for simple place forms. In the simple `cl-defsetf' form, `cl-setf's of |

7c1898a7 SM |
1910 | Alternate form: (cl-defsetf NAME ARGLIST (STORE) BODY...). |
1911 | Here, the above `cl-setf' call is expanded by binding the argument forms ARGS | |
fcd73769 | 1912 | according to ARGLIST, binding the value form VAL to STORE, then executing |
