- actually in the same big org-mode file (unless I call something from
  some yasnippet snippet, but I don't think)
- yes maybe also variables
  But variables can be assigned to a group also (with defcustom) so it's
  not so bad
- yes really all functions (some have the "my-" prefix but that can be
  changed easily I think)

And since I'm here, why I can't redefine a variable with defcustom?
I mean if I do

(defcustom x 1)
then I want to change it
and I write and evaluate
(defcustom x 2)

then even if I set it to nil and the reevaluate again still it doesn't
care.
Is that normal?
