The flaw is that Ada has no 'polymorphic array type': an array that has an
indefinite component subtype.
As I suggested in a post a few months ago, such an array type would be easy
to add to Ada's existing syntax, easy and efficient to implement (as an
array of pointers plus a ragged sequence of objects, internally), and very
bloody useful, pardon the language. (It would have solved Bruce's problem in
a trice.)
Maybe come the next review...
