Perhaps in the complicated cases, but in the common and simple case that the OP's talking about (where the purpose of the outermost function is solely to capture arguments for the next level in), I wouldn't bother with a class. But as you say, YMMV. ChrisA -- https://mail.python.org/mailman/listinfo/python-list
