in langage like rust a slice is a kind of special pointer to an array or
any list with 3 coords like arrayref,position, length.

dim myarray as array = [...,...,...

dim mySlice as Slice = MyArray.Slice(2,23)

for each s in MySlice
...

I you change value in array then the value change also in the slice as it
is just a pointer to an array part.

It can be usefull on string analysis.
