From OpenEUO
unpack (list [, i [, j]])
Returns the elements from the given table. This function is equivalent to
return list[i], list[i+1], ···, list[j]
except that the above code can be written only for a fixed number of elements. By default, i is 1 and j is the length of the list, as defined by the length operator (see §2.5.5).
