Below what the `Messages" buffer tells me:

command-execute: Wrong type argument: commandp, interactive-aware-fun
Mark set

Here the excerpt from the initialization file:

(defun interactive-aware-fun ()
    (message "interactive-aware-fun called-interactively-p : %s" (called-interactively-p))
)
(interactive-aware-fun)
(global-set-key (kbd "<f9>") 'interactive-aware-fun)

Why does a F9 press give me the message:

command-execute: Wrong type argument: commandp, interactive-aware-fun

? I am doing similar things in the initialization file and all work ok. This one gives me this message instead of the output the function provides if called from the initialization file.
