PLEASE, PLEASE, PLEASE give your views on the example I quoted from
cc-defs.el. I am getting very frustrated that people seem to be evading
my main point, namely that code like
;; Make edebug understand the macros.
(eval-after-load "edebug"
'(progn
(def-edebug-spec cc-eval-when-compile t)
(def-edebug-spec c-point t)
(def-edebug-spec c-set-region-active t)
....
))
is not merely acceptable, but is an epitome of clear and efficient
coding. If I am wrong here, then please educate me, bring me to
understand HOW I am wrong.
Given that CC Mode is intented to be compatible with many (X)Emacs
versions, nearly all of which lack the `declare' feature in defmacro, I
cannot see how I can get along without eval-after-loads like the above.
I do not understand why you regard eval-after-load as objectionable.
Just because it can be used in an objectionable fashion does not make it
objectionable per se.
It seems to me that eval-after-load is essential in the following
circumstance:
A package (say, CC Mode) must tweak something in an optional library
which a user may choose to load (say, font-lock[*] or edebug) in order
to work satisfactorally with it.
[*] Yes, I know that font-lock is now pre-loaded, but it didn't used to
be.
I believe that Emacs should NEVER clutter up a user's ram by loading
libraries he will not be using. Not edebug, not Info, not Font Lock[*].
Unless there is a better way of doing things, I do not want to take the
eval-after-loads out of CC Mode. Please tell me that this is OK.
