I have sympathy for this feeling, and I see many people falling into that trap, but to be fair:
Do you know ANY language that allows it ?
Most OO languages (C++, Java, Eiffel, even Turbo-Pascal) do not allow declaring classes within a subprogram.
In Ada, all classes must be declared at the same level. In other languages, all classes must be declared at level 0.
So Ada is actually *more* permissive than other languages...
