I'm not following this thread, so ignore if this question doesn't help:

Why set up autoloading here?  Seems like you would want to either soft-require
the library (no error if not there) or simply test whether the function is
defined (which presumably happens when the library is loaded).

IOW, why don't you just choose between (require 'foo nil t) and (fboundp
'foobar)?  What's the point of having this library autoload the other one but
not soft-require it?

(FWIW, it sounds a priori like you should maybe just use the `fboundp' test, and
not worry about automatically loading the other library.)

Again, ignore if irrelevant to your discussion.
