Everything is smoke and mirrors with software.  When Illustrator makes a 
"symbol" it's still a copy, but maintains a reference to some source 
object from which its properties are derived.

With Rev, we have:

    set the properties of <obj> to the properties of <obj>

You can also modify the properties array - for example, this will assign 
the properties of one button to those of anothe but allow the 
destination object to keep its own name, label, and rect:

on mouseUp
   put the properties of btn "aaa" into tObjA
   delete var tObjA["label"]
   delete var tObjA["name"]
   delete var tObjA["rect"]
   set the properties of btn "bbb" to tObjA
end mouseUp
