If you prefer, think of it something like: The fact that you can make it somehow work, doesn't mean it makes much sense. If you don't like the limitation of the assignment semantics in python, it seems more interresting to change that, than to work around what we have now. Python could go the simula route, which has two kinds of assignment. One with the python semantics and one with C semantics. Let as use := for the C sematics assignment and <- for the python sematics assignment. We could then do something like the following. ls := [5, 8, 13, 21] a <- ls[2] a := 34 print ls # [5, 8, 34, 21] Now it may very well be possible to achieve the same results with what you have in mind, but in my mind it makes not much sense in trying to achieve the semantics of a copy assignment by building extra indirection on top of reference assignments. -- Antoon Pardon
