bug#19564: 24.4; eieio backward compatibility

I don't think so:

   (defmacro oref (obj slot)
     `(eieio-oref ,obj (quote ,slot)))
   (defalias 'slot-value 'eieio-oref)

They both accept the slot name (except that one needs it quoted and the
other doesn't) and the initarg name (as an alternative name for the
slot).

Could be, indeed.  I haven't looked enough at EIEIO's own documentation.
