Ada doesn't have "partially private" records -- what you're talking
about seems to be a special case of that. There are several reasons
for this: it doesn't fit with the idea of 'private' (if you can fiddle
with part of a record, it breaks the abstraction) and it's extra syntax
for something with much cleaner alternatives (accessor functions),
Private tagged types have effective public bits (the tag) but this
is a Good Thing. In any case, why would you ever have non private
tagged type? Doesn't that defeat the purpose?
