Subject: 26.3; The info doc of eieio-class-name is outdated and its value
 looks incorrect
Date: Sun, 24 Nov 2019 23:11:10 +0800
(info "(eieio) Predicates") mentions

 -- Function: eieio-class-name class
     Return a string of the form ‘#<class myclassname>’ which should
     look similar to other Lisp objects like buffers and processes.
     Printing a class results only in a symbol.

but it is not right, the value is not string at all, it's a symbol

  (defclass my-class () ())
  ;; => my-class

  (eieio-class-name 'my-class)
  ;; => my-class

  (type-of (eieio-class-name 'my-class))
  ;; => symbol

The git master produced the same result as Emacs 26.3. I notice Emacs
24.3's class-name produces the expected result and the function is
replaced by eieio-class-name since 24.4

   (define-obsolete-function-alias 'class-name #'eieio-class-name "24.4")

however, these two functions are different. It seems eieio-class-name
contains a bug, the name suggests its value is a string, but it
returns a symbol.
