Thats exactly right. your __of__ method means that *any* time you try
to take a B object out of an A, you get a C
Here is a simple code:
from Acquisition import Implicit, aq_base
class A(Implicit): pass
class C(Implicit): pass
class B(Implicit):
def __of__(self, parent):
# controls the wrapper used for acquisition
c = C()
c._parent = parent
return c.__of__(parent)
