Please do not do this. As someone (may have been John Max Skaller) on
comp.lang.c++ said once, "casting is something you do when fishing".
Think about what you are trying to do, and try to figure out how this
can be accomplished by the tools available to you in Ada, like
generics or run-time polymorphism.
