# 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 The Length Operator).
