rementioned languages, one could index with the value 1 to get the first el=
ement, or index with a vector [2, 3, 4] to obtain a vector of the 2nd, 3rd =
and 4th elements.=20

If I understand correctly what you want, it is built-in in Ada:

   type Arr is array (positive range <>) of Natural;

   V : Arr (1 .. 78);

Then

   V (1) is the first element (a Natural)

   V (2 .. 4) is an array of 3 naturals with first index being 2
   and last 4.
