But the thing to note here is that this rule is not some
kind of annoying arbitrary restriction, it is quite
fundamental. When you change the discriminant, you change
the contents of the record that are accessible, it is
therefore ESSENTIAL to assign the record contents at the
same time, otherwise you could get garbage values being
suddenly accessible.
