Why not?  Is that because of this thing you also wrote in the same message: "use lists are 
allocated before the object"?

Trying to sort a container of such objects doesn`t require me to contradict that advice.  The 
code I have added only uses "GlobalVariable" via pointers and references, with the possible 
exception of the newly-added copy ctor.

Thanks for your reply.
