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?

Cheers,
Chris
