defvar creates a hook variable.
run-hooks associates some-hook with the some-function.

Now one writes lambda functions associated with the some-hook
without modifying the some-function????

Is that the idea? The post was incomplete. Perhaps the author
know too much for us. But I want a simple concrete minimal example
of running code.
