Hi,

In Algol60 language (40 years ago) it was possible
   to work with arrays with various boundaries.
For example,
        array [5 : 20] is {a[5], a[6], ..., a[20]}
        array [-7 : 3] is {a[-7], a[-6], ..., a[3]}

In C/C++ we can work only with arrays
        {a[0], a[1], ..., a[size - 1]}.

The STL vector class is also vector
        {v[0], v[1], ..., v[size - 1]}.
There is no array/vector class with various boundaries
(I would like to be mistaken, but it seems I am not mistaken).

I have designed me own ClassFlexibleVector with various boundaries.
But I would like to use standard classes.

I don't ask why arrays with various boundaries are missing in C/C++.
But why are they missing in STL?
It was in Algol60.

        Thanks in advance,
        Alex
