In Gnorb I've tried to make the various components (Org-focused,
Gnus-focused, BBDB-focused) loadable separately, by protecting some
setup with `eval-after-load'. In `gnorb-install-defaults' I tried to get
clever and use nested `eval-after-load's, so that some keys are bound
only if the user has elected to use, eg, *both* the Org and BBDB
functionality. `gnorb-install-defaults' has bits in it like this:
(eval-after-load "gnorb-bbdb"
'(progn
(define-key bbdb-mode-map (kbd "C-c S") #'gnorb-bbdb-mail-search)
(define-key bbdb-mode-map (kbd "C-c l") #'gnorb-bbdb-open-link)
(define-key bbdb-mode-map [remap bbdb-mail] #'gnorb-bbdb-mail)
(eval-after-load "gnorb-org"
(org-defkey org-mode-map (kbd "C-c C") #'gnorb-org-contact-link))))
This raises an error if the user loads "gnorb-org" and *then*
"gnorb-bbdb". What seems to happen is that first the "gnorb-org" form
is evaluated, and its return value (the function object
`gnorb-org-contact-link') is stored in the outer `eval-after-load'. When
"gnorb-bbdb" is loaded and the outer `eval-after-load' is evaluated,
`gnorb-org-contact-link' is actually run as a function (and complains
about wrong number of arguments).
I had assumed that the entire outer `eval-after-load' form would remain
"frozen" until "gnorb-bbdb" was loaded, at which point the inner
`eval-after-load' would be evaluated and either define the key or
"freeze" the inner form, depending.
Is there a better way to do this?
Thanks,
Eric

Missing quote for the inner eval-after-load?

Bah, I was staring right at it, and even had it right in other places in
the same function. Thanks for that.
