My CK> elisp is atrocious, but in Common Lisp I envision something like: Sure. There's a old hack out there to make "defcustom" work even when custom.el isn't available. CK> (handler-case (symbol-function 'avl-tree-something) CK> (undefined-function () CK> (setf (symbol-function 'avl-tree-something) (symbol-function CK> 'avltree-something)))) CK> We could have a bunch of these as top-level forms (one for each CK> avl-tree-* function we need to use). They would detect if CK> #'avl-tree-something is undefined, and if so, define it to be the same CK> function as #'avltree-something. Something like this might work.... (if (not (require 'avl-tree nil t)) (progn (require avltree) (defalias avl-tree-enter 'avltree-enter) (defalias avl-tree-delete 'avltree-delete) .... ))
