I've been bitten by this once or twice in the past, but I have always
wondered what it was useful for? Can anybody enlighten me?
As an optimization, inside a method, you can bind an instance
attribute and a local name to the same object:
def some_action(self):
self.items = items = []
// following many references to self.items,
// but using items instead.
Names in the local namespace are resolved at compile time, so using
items is a lot faster than looking for "items" inside self's
namespace each time it's used.
