You would need to arrange for your ZClass to create a new
Confera _instance_ in your new object instance at construction
time. If you plopped a Confera instance into the actual ZClass,
that Confera instance would be shared by all instances of that
ZClass - this would be the case for _all_ mutable objects,
exactly like in python. 

For example, to create an object where each instance has its
own list attribute (mutable object) in Python, you would do:

class foo:
  def __init__(self):
    self.data=[]

You would _not_ do:

class foo:
  data=[]

...because all foo instances would share the same data list.

Hope this helps!
