Perhaps another way of viewing this issue (following the discussion from
Mark) is to ask who controls the private/public (i.e., data hiding)
distinction. In Ada this is done on the package level, where as the
example with private/public components ties the distinction to the type -
as in C++ classes.
In many cases the Ada approach is easier to understand, and enhances
readability. But there can be other cases (perhaps like the one that
prompted this discussion) that are more natural to express using the other
approach.
I am not sure that I can prove which is the better approach, but I agree
that it seems like a core design principle of the language.
