I wonder why. That's an interesting question. One reason might be that in the absence of static type analysis, assigning to a variable holding a reference to another variable would be ambiguous. For example, suppose Python had an & operator that gives you an object referring to a variable somehow. Then, after a = 42 b = 17 c = &a c = &b does 'c' now hold a reference to the variable 'b', or does it still hold a reference to 'a' and 'a' now holds a reference to 'b'? Somehow these two operations would have to be spelled different ways, which means you would need to know whether you were dealing with a variable reference or not. So they wouldn't really be first-class, in the sense of being treated on an equal footing with ordinary variables. -- Greg
