[Zope] Sub Class Question

[Loren Stafford]

I'm not sure if this is the same situation I encountered in Xron's
XronDTMLMethod.py, where I'm overriding CatalogAware's index_object method.

  # Only index if nextEventTime returns something
  def index_object(self):
    if self.nextEventTime() is not None:
        CatalogAware.index_object.im_func(self)
        # see Python Reference Manual "The standard type hierarchy"
        # for the built-in type im_func
