tuple_uniq discards all but one of successive identical
elements from the input tuple Tuple and
returns the remaining elements in Uniq. For
example, if Tuple contains
the values [0,0,1,1,1,2,0,1], the output tuple Uniq will
contain the values [0,1,2,0,1]. It is allowed to mix strings and numbers in the input tuple. To delete really all identical elements of the input tuple, use first the operator tuple_sort.
