Michal> does the type() command work correctly for new style classes?
Yes. Using 2.2:
>>> class A(object): pass
...
>>> type(A)
<type 'type'>
>>> type(A())
<class '__main__.A'>
>>> isinstance(A(), A)
1
Using 2.3 or newer:
>>> class A(object):
... pass
...
>>> type(A)
<type 'type'>
>>> type(A())
<class '__main__.A'>
>>> isinstance(A(), A)
True
In general, you shouldn't be using the types module, certainly not for
new-style classes.
