We had an idea. You can use ~ to convert the index to the array which always
starts with 0. Then we can use negative indexes, and you can always find the
beginning of the array.
Example:
we have array [-3:3]={1,2,3,4,5,6,7}
array[~0] == 1
array[~-1] == 7
array[~2:~-2] == {3,4,5,6}
What do you think?
