I really distaste this "etc." in your description. In the end you promote endless lists of command line parameters to configure every possible function. I also doubt that the solution is more clean but arbitray instead. My own guess why properties are not promoted with more emphasis is that they lead to cargo cult programming i.e. everyone starts to use property syntax even when usual attributes are sufficient. So the syntax might even be intentionally ugly. -- http://mail.python.org/mailman/listinfo/python-list
