This script allows you to get the object name literal as string.
It works as long as caller property is supported and as long as a call
chain is presented (thus one could backtrace to the holder of the
literal).
A need of such script is more than questionnable. I guess these
literals just got me of being too dazzling: you see them, you can touch
them, but you cannot get their damn name despite it's just in front of
you. :-)
