I am writing some lisp hacks in emacs lisp and I won't handle this
code:
(defun make-length-list (coord)
(when coord
(cons (- (cadar coord) (caar coord))
(make-length-list (cdr coord)))))
when cadar and car are not recoginzed by elisp. make-length-list
reads a series of pairs ((100 200) (300 450) (500 700)) and is
supposed to return a cons-list of their difference (100 150 200). I
like lisp but obviously I am not very clever.
