I don't think there is any rationale.  It makes perfect sense
for them to be visible, but they're not.  I guess it was just
a minor mistake in Ada 83, and it's never been thought important
enough to fix in later versions.  I don't see any way in
which this rule "preserves type privacy".

Note that the rule is different for generic formal packages.

Your workaround is OK.  I've done that.  But it presents an
annoying problem -- you have to think of two different names for the
same thing.
