如何更改函数体执行的顺序?

我正在按照介绍学习Emacs Lisp。

我可以理解下面的defun按从左到右的顺序打印列表,因为打印命令在递归之前出现(正如我所理解的):

  (defun print-elements-recursively (list)
   "Print each element of LIST on a line of its own.
 Uses recursion."
   (when list                            ; do-again-test
         (print (car list))              ; body
         (print-elements-recursively     ; recursive call
          (cdr list))))                  ; next-step-expression

E、 g.列表 '(gazelle giraffe lion tiger) 。打印顺序为 gazelle , giraffe , lion , tiger .

然而,我无法理解当我在 when 正文:

(defun print-elements-recursively (list)
   "Print each element of LIST on a line of its own.
 Uses recursion."
   (when list                            ; do-again-test
                       ; body
         (print-elements-recursively     ; recursive call
          (cdr list))
         (print (car list))))                  ; next-step-expression

按照我的预期,递归发生在 print 因此,顺序应该颠倒。我可以知道为什么吗?
