That depends on the implementation, I think. I doubt that early ones will be 
that great, but I expect it to get better over time.

Maybe, but you'd never write one of those in Ada 2012 anyway. You'd instead 
write:

    for E of My_Container loop
        <do whatever with E>
    end loop;

Here again, I expect early implementations to be an exact translation to the 
"canonical" code (probably not that wonderful), but later versions most 
likely will be better.

                            Randy.
