Whoops, sorry for the hasty answer. I usually use eieio-oref, which
is a function and wants a symbol. `oref' is defined as a macro:

(defmacro oref (obj slot)
  (declare (debug (form symbolp)))
  `(eieio-oref ,obj (quote ,slot)))

I've always been a little confused about whether one thing or the other
was preferred.
