Given all these possibilities (but even with only enough basic
data types), I think there might be an interesting
way to store (tagged) program objects in a DB and make use of the new
Ada.Tags.Generic_Dispatching_Constructor. The effect would be a
straightforward function that delivers objects of suitable type
based on (a) search results and (b) program need.
