Therefore I propose that Python includes >built-in support for reducing the ``self.x=x`` clutter. With some help from new-style classes you can get more than just removing the "self.x = x" clutter. I'm not an expert of these low-level python tricks, but you can download from http://www.gripho.it/objs.py a small example that allows you to write class MyClass(Object): x = Float(default = 0.0, max = 1E20) y = Float(min = 1.0) and you can get in addition of redudancy removal also parameter checking. You can also have an __init__ method that gets called with attributes already set up. HTH Andrea -- http://mail.python.org/mailman/listinfo/python-list
