The package represents the object ("object" being a design concept). The
variables in the pkg body represent the state of the object, same as the private
fields of an object represented by an instance of a tagged type (or a "class"
type in some other languages). Note the use of State for the hidden variable in
Andersen's example, and the SPARK "state" annotations for such packages.
