Well, yes, due to backward compatibility -- though how much code is
counting on not being able to add attributes to an instance of object?
I think someone on this thread (sorry can't find it now) said something
like:
if you could add attributes to object(), then you'd be able to add
attributes to subclasses of object. -- but you can already:
Isn't every class a subclass of object?
class C:
pass
C.this = "something"
c = C()
c.that = "something else"
It seems the difference is that both a new class and class instances get a
__dict__. But given that all classes derive from object, and object is of
type type, and classes are of type type -- I still have no idea why we
can't add things to an instance of object.
I suppose adding stuff to the object class itself would be very weird -- as
that would mess with ALL classes. But adding to an instance of object? why
not?
