c.x = 4 already updates the instance dict, so there's no need to change any class methods to support it. That is, IME it's much better to add methods to a regular class to make it more dict-like using the built-in instance dict rather than changing any of the attribute mechanisms. If you're really curious, I recommend trying several approaches yourself to see what works better. ;-) -- Aahz (a...@pythoncraft.com) <*> http://www.pythoncraft.com/ "If you think it's expensive to hire a professional to do the job, wait until you hire an amateur." --Red Adair -- http://mail.python.org/mailman/listinfo/python-list
