Subject: bug#18494: 24.4.50; defclass creates undocumented *-list-p function
Date: Wed, 17 Sep 2014 20:09:57 -0600	[thread overview]
Message-ID: <87a95xvfuy.fsf@tromey.com> (raw)


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.
