objects... you end up with code like

deepcopy(var1, var2);

or maybe

var1.Assign(var2);

instead of

var1 = var2;

My thought after reading this thread was:

var1 = var2:Duplicate(); or
var1 = var2:Copy()
neither of these affect the C++ object that is wrapped by var1, var1 instead gets a new pointer to wrap (being a copy), and the old one is garbage-collected.
If you want to modify the pointer that var1 wraps, then var1 needs to be involved in the function that does the assignment.

I do this in some of my Lua code and it works pretty well. I find it makes it pretty easy to tell when a new resource is allocated vs. simply referenced in a new way. 

Of course what's clear to me, may be mud to others...
