I don't follow this at all. You say your justification "is not only for 
strings" but only give a string example. And what you want is essentially 
the semantics of a vector container (more specifically, a bounded vector 
container), but want to add a pile of additional complication to something 
that is already far to complicated. What's wrong with building around a 
bounded vector??? Ada (or its successor) needs to be simpler, not more 
complicated.
