Do we still need to inherit from "object" to create new-style classes?

Lib ref 2. builtin functions:
"object()
Return a new featureless object. object is a base for all classes. It 
has the methods that are common to all instances of Python classes. This 
function does not accept any arguments.

Note
object does not have a __dict__, so you can’t assign arbitrary 
attributes to an instance of the object class.

What page? *It* may need updating ;-).

The core 3.x docs have been updated by removing all reference to 
old-style classes and the modifier 'new-style'. The concept 'new-style' 
only exists in opposition to 'old-style'. 3.x just has classes, and all 
are subclasses of object.
