Eval the following code

  )
(when nil
  (cl-define-compiler-macro yes (&rest _)))
;;;; END

,----[ C-h f yes RET ]
| yes is a Lisp function.
| 
| (yes)

| This function has a compiler macro `yes--cmacro'.
| 
| Not documented.
| 
| [back]
`----

how is it possible? the compiler macro is defined at macro expansion
time?
