--- Comment #14 from Chris Paulson-Ellis <ch...@edesix.com> --- Also - to emphasise what was said in comment 11 - let me just say that it took me *3 days* to find that the cause of a mysterious crash in my code was the destroy in nullify(). At the very least, the documentation for Nullable should contain a prominent warning that nullify() will invalidate your class references. --
