Two observations: In Python you can also use "duck-typing" -- if you don't want to share code between the classes there is no need for an inhertitance tree at all. Pagination is a matter of display and will be handled differently in a PDF document or web page, say. I would not make it part of the data structure. -- https://mail.python.org/mailman/listinfo/python-list
