That one did not work, it was demonstration that it does not work. 

And here again the solution which does work:

(defvar my-doc "Hello there")

(defmacro my-fun ()
  `(defun my-fun ()
     ,my-doc
     (ignore)))

To define function run: (my-fun) ⇒ my-fun

(documentation 'my-fun) ⇒ "Hello there"

Funny, as to define the function one defines macro that
overwrites itself by the function calling the macro first time.
