Now I´m slowly getting the point of this...it´s the combination of
private, limited and the unconstrained type. If I don´t declare it as
private and limited, I would be able to instantiate it, because it is
visible outside the package? In this case I would be able to assign a
value when declaring an instance and thus I would of course be able to
create as many instances as I want to? Is this right?
