You're still defining the class, so how could there possibly be an instance of it to refer to as "self" yet (outside of a method body)? Also, just so you know, default argument values are only evaluated once, at the time the function/method is defined, so `pos = self._value` is never going to work. Do you mean for self._value to be a class variable (Java lingo: static variable), or an instance variable?
