Hi! I am also concerned about performance. I really love the object-prefix notation but "it's only available for tagged types" (i.e. type Car_Type is tagged private;) and thus I also avoid tagged types except for when applicable (i.e. large types i.e. containers). I make heavy use of "use all type" instead. Needless to say I am also curious about using tagged types in custom indexers and iterators.
I don't know of a nice solution to your specific case in the Ada language. If you use aliased parameters and implicit dereference you will expose the whole of your buffer not part of it. The cleanest way forward is for you to use a generic function that will expose part of your array. To see an example of this see "procedure Act_On_Immutable_Text (..) " in the Aida.Bounded_String package:
https://github.com/joakim-strandberg/aida_2012/blob/master/config/aida_src/aida-bounded_string.ads
Another thought on performance is avoiding controlled types where possible.
Best regards,
Joakim
