I've long felt that publicly accessible attributes probably should be syntactic sugared to look like accessor methods, a bit like how __add__ ends up being + - so that if your attribute ever needs to become methods (say, it started out life as a unidimensional thing, but later needs to be a flattening of 3 dimensions or something), you won't necessarily need to change depenent code. But are methods a lot more expensive in python than referencing other kinds of attributes? -- http://mail.python.org/mailman/listinfo/python-list
