Since we seem to be discussing various Ada features...
I was always ready to defend Ada's lack of automatic instnatiation, but I
seem to be loosing me resovle.
Maybe some one can re-convince me ;-)

For the purposes discussed here, I would be happy with a solution allowing
me to create partial instantaions, so that only the top level would need to
be instantiated by the user.
(This is close to "template specialization", I think, but not exactly the
same thing).
Is there any elegant idiom for doing this?
(If I am not clear, I'll try to post an example).
