Could you elaborate on what im_func is and what it's role is here. Does it have to do with mapply? I see it used there, but don't understand what's going on.

# Only index if nextEventTime returns something def index_object(self): if self.nextEventTime() is not None: CatalogAware.index_object.im_func(self)

im_func is a part of Python introspection. It is the pure function definition of a class, not bound to that class, so I can pass in an alternate self. I am trying to call a superclass method here, and normally CatalogAware.index_object() would suffice. But because of Extension Classes, Python gets confused as to what is a class method, and what is a regular function. It will accuse me of calling an unbound method, which of course I am not. I circumvent this by calling the unbound function, and passing in self explicitly.
