-;;; Commentary:
-
-;; Backward compatibility definition of old EIEIO functions in
-;; terms of newer equivalent.
-
-;; The main elements are the old EIEIO `defmethod' and `defgeneric' which are
-;; now implemented on top of cl-generic. The differences we have to
-;; accommodate are:
-;; - EIEIO's :static methods (turned into a new `eieio--static' specializer).
-;; - EIEIO's support for `call-next-method' and `next-method-p' instead of
-;; `cl-next-method-p' and `cl-call-next-method' (simple matter of renaming).
-;; - Different errors are signaled.
-;; - EIEIO's defgeneric does not reset the function.
-;; - EIEIO's no-next-method and no-applicable-method can't be aliases of
-;; cl-generic's namesakes since they have different calling conventions,
-;; which means that packages that (defmethod no-next-method ..) don't work.
-;; - EIEIO's `call-next-method' and `next-method-p' had dynamic scope whereas
-;; cl-generic's `cl-next-method-p' and `cl-call-next-method' are lexically
-;; scoped.
