Mms, thanks for arising my curiosity on the subject -
actually, there is very elegant solution to make class no
inheritable and allow it on stack. The idea is to virtually
inherit from base class with private destructor. Virtual
inheritance will force derived classes to call virtual base
destructor first, and it would be impossible because its is
private. Much better than solution I described, must admit.
Ok, here is the link with very good description :
