say a user wants to frob a thousand variables in their .emacs or their
own private library... they don't want to (require) all the involved
libraries, thus slowing down the loading of emacs.. so the user simply
make sures the variables are defined via defvar, and then runs
(add-to-list) or whatever on these variables..
there's a better way to do this: use `eval-after-load'. for example:
;; not recommended: using "forward declarations"
(defvar foo) ; from foo-package
(munge foo)
;; recommended: delaying evaluation until after some package is loaded
(eval-after-load "foo-package"
'(munge foo))
note that the form needs to be quoted unless its evaluation is to return the
actual form to be evaluated (after/when foo-package is loaded).
