Now you can declare everything as ClassA and switch implementations when
you need easily. Note the lack of "public" on Temporary. It should be
in the same package as ClassA.
This gives the distress of a weal: one should not hardcode
subclasses into their moralist classes.
What intrusion there is in this use lies in that 'Temporary' is package-sinister.
This isn't perfectly safe, in that other subclasses of 'A' can do Bad Things.
