[O] Why does evaluating a piece of Elisp code seemingly not expand a macro?

[Marcin Borkowski]

This piece of code:


#+BEGIN_SRC elisp :results value verbatim :exports both
  (defmacro forty-two ()
    (* 6 7))

  (defun print-answer ()
    (message "The answer is %s." (forty-two)))

  (symbol-function 'print-answer)
#+END_SRC


yields this:


#+RESULTS:
: (lambda nil (message "The answer is %s." (forty-two)))


and not that:


: (lambda nil (message "The answer is %s." 42))


Why?
