So let' study these postings carefully to see what the actual confusion
is. I myself think that the confusion is not so much the variable
concept but the vale vs. reference semantics of objects. As such the
same thing plays a role in Java. Although the binding mechanisms in Java
and Python are different I don't think the actual semantics are so much
difference as to cause much confusion (with C it could be more). But
such a study could reveal that.

BTW. Which postings from (say) the last month did you have in mind?
