Hi,
The second behavior below seems like a bug to me. It was not
present in emacs 23.1
Best wishes,
Rafael Sorkin
emacs-version ; 23.1.1
(setq pair (cons 3 4)) ; (3 . 4)
(foobar pair) ; Symbol's function definition is void:
foobar
(setf (foobar pair) 0) ; No setf-method known for foobar
(unless t
(defalias 'foobar 'cons)
(defsetf foobar setcar)) ; nil
(foobar pair) ; same as above
(setf (foobar pair) 0) ; same as above
pair ; (3 . 4)
emacs-version ; 24.5.1
(setq pair (cons 3 4)) ; (3 . 4)
(foobar pair) ; Symbol's function definition is void:
foobar
(setf (foobar pair) 0) ; (foobar pair) is not a valid place
expression
(unless t
(defalias 'foobar 'cons)
(defsetf foobar setcar)) ; nil
(foobar pair) ; same as above
(setf (foobar pair) 0) ; 0 !
pair ; (0 . 4) !
