Try:

(defclass zzz-whatever () ((hi)))

Now notice there is a new function:

(symbol-function 'zzz-whatever-list-p)
(lambda (obj) "Test OBJ to see if it a list of objects which are a child of type zzz-whatever" (when (listp obj) (let ((ans t)) (while (and obj ans) (setq ans (and (eieio-object-p (car obj)) (object-of-class-p (car obj) zzz-whatever))) (setq obj (cdr obj))) ans)))


This new -list-p function is not documented in the EIEIO manual.

It seems to me that it would be a bit better not to define it.
It doesn't seem generally useful enough, to me.

However, if it is kept, it ought to be documented.
