I'm still of the opinion that we (the ARG) gave up too soon on this problem. 
In any case, it's still on the ARG's radar (see AI05-0074-1 and AI05-0074-2) 
although looking at extensions is not a high priority right now.

In any case, it isn't allowed in any version of Ada. You'll have to use 
another (less elegant) solution, such as the child package or reexported 
operations suggested by others.
