The fact that all (well I'm not sure, that's so long ago that I could
program in Ada, and it make me think about freezing rules that I've
never really mastered) subroutines defined in the same package as a
type having that type as argument or result are primitive operations
is sometimes annoying, but there is an easy work around: provide it in
a nested package and then use a renaming.
