Gem #27: Changing Data Representation (Part 1) by Robert Dewar
explains how to use type derivation if you want to have two
representations of the same data. The types let you convert
between an external and an internal representation, say.
IIRC, this is feature of Ada 83 and has been text book material
at the time. Has it got lost in modern times introductions
to Ada 95 and later? How can a valuable, venerable basic
facility for problem solving be missed?
<p mode=bold>Maybe authors and instructors have not come across
these features because the features are not easily available in
the non-Ada languages with which they have learned programming?</>
