I'm a little confused with this whole thread. I didn't think that using
the "magic" methods (or metaclasses) was a recommended Python programming
practice. While it might be elegant to the person programming it, to less
proficient programmers, it looks confusing. Maybe I'm just being nitpicky
though. Aren't there some standard "setters" and "getters" ?
