In the initialiser you can either use @auto.. or self.auto.. The
latter will use the accessor. This is necessary even if you change
the parameter name in the initialiser so that it is not the same as
the accessor.
It seems that in fact you do not need either in calculator_neto but I
am not sure why it is necessary in the initialiser but is not
necessary there. Probably someone more knowledgeable will explain.
