(setq my-test (make-instance 'testclass))

(eieio-oref my-test 'num)
;; ==> Error because of private

(testclass.num my-test)
;; ==> 1, Can get a private value!!

Accessor should be unable to access private data.

It's documented in the EIEIO manual that the :protection slot has no effect.

(info "(eieio) Slot Options")

‘:protection’
     This is an old option that is not supported any more.
[...]
     This protection is not enforced by the code any more, so it’s only
     useful as documentation.
