;;; Commentary:
;;
;; The eieio-persistent base-class provides a vital service, that
;; could be used to accidentally load in malicious code. As such,
;; something as simple as calling eval on the generated code can't be
;; used. These tests exercises various flavors of data that might be
;; in a persistent object, and tries to save/load them.
