The function is called by the hi-lock-mode itself. I used defalias in
another mode. It´s basically like this:
in mode A:
(defun mode-a-function-one (mode-a-function-two))
in mode B:
(defun mode-a-function-two-replacement)
(defalias 'mode-a-function-two 'mode-a-function-two-replacement)
(defun mode-b-function (mode-a-function-one))
It was possible to re-define 'mode-a-function with mode B, provided that
mode A was already loaded at the time the function was re-defined ---
which makes sense because otherwise there is nothing to re-define, and
mode A may even re-define the function of mode B when it´s loaded after
mode B is loaded. The defalias somehow didn´t kick in.
Defadvice shines. I wonder who invented that ...
And re-defining functions just like that? Isn´t that a rather dangerous
and potentially troublesome feature?
