(* 
   [slice] is the type of Word8Vector slices, that is, sub-vectors of
   Word8Vector.vector values.
   The slice (a,i,n) is valid if 0 <= i <= i+n <= size s, 
                or equivalently, 0 <= i and 0 <= n and i+n <= size s.  
   A valid slice sli = (a,i,n) represents the sub-vector a[i...i+n-1],
   so the elements of sli are a[i], a[i+1], ..., a[i+n-1], and n is
   the length of the slice.  Only valid slices can be constructed by
   these functions.

   All operations are as for VectorSlice.slice.
