This already exists, although with a slightly different syntax:

type String_From_1 (Length : Natural) is record
    Value : String (1 .. Length);
end record;

But perhaps it would be a good idea for a new language to have separate sequence 
types with positions but no indices? Such a language would only need constrained 
array types to serve as maps.
