Hi.

Let us say that file "foo" is "loadable" if either foo.elc or foo.el
is in one of the directories in the load-path.

I would like to do the following:
  
   IF foo is loadable THEN
      (autoload 'foo-mode "foo" t t nil)
   ELSE 
      (autoload 'foo-mode "bar" t t nil)

The obvious thing would be to defun a predicate loadable-p, and
procede from there.  Is there anything built-in that I can use, and so
avoid re-inventing the wheel?  Clearly emacs itself has to search the
load-path whenever it has to do a load or autoload.  How can I use
this built-in ability?

Thanks.
