Wrong. Python has objects and targets. Names are a subset of targets.
A target is anything that can contain a binding (or reference, whichever
term you prefer) to an object; lists are arrays of targets.
No matter how you slice it ;-), a list does not actually hold objects, it
only holds references to objects.
