Ok now i am completely confused.
After reading your linked source i am back at my starting point, asuming 
the only value assigned by reference is a table/list. All other are 
assinged by value. So a
_stringvar1= stringvar2_ creates a copy of the source string.
(still assuming we are talking about strings of size 1kB+ as in my program.)
