Well, I guess this shows how lacking I am in C++. I genuinely thought
auto_ptr was a kind of memory manager, less thin that what is described
in Wikipedia.

Anyway, I still see the use of the thing I thought was auto_ptr, and
others pointing at implementations seems to confirm this usefulness.
However I still don't really understand why it's not part of the
standard, but I guess I will be more able to judge how useful it really
is in Ada after having much more Ada practise.


Thanks for correcting me,
