That is impossible to define, though, because some people are mental acrobats and can do a lot of deep analysis in their heads. What's satisfactory to you may not be satisfactory to me. Besides, looking for "satisfactory" patterns can involve a truckload of trial and error. Marko -- https://mail.python.org/mailman/listinfo/python-list
