> The hook functions mostly talk about symbols and hooks, not variables, and

I also expected so, but I've already changed a handful of
`(run-hooks 'foo)` to `(mapcar #'funcall foo)`.  The problem is a bit
different, tho: it's *also* wrong to use it on dynamically-scoped let-bound
vars (tho it mostly works), so the doc should not focus on lexical
vars but on the difference between vars and hooks.
