 @end deffn
 
+@deffn {Function} unique (@var{L})
+
+Returns the unique elements of the list @var{L}.
+
+When all the elements of @var{L} are unique,
+@code{unique} returns a shallow copy of @var{L},
+not @var{L} itself.
+
+If @var{L} is not a list, @code{unique} returns @var{L}.
+
+Example:
+
+@c ===beg===
+@c unique ([1, %pi, a + b, 2, 1, %e, %pi, a + b, [1]]);
+@c ===end===
+@example
+(%i1) unique ([1, %pi, a + b, 2, 1, %e, %pi, a + b, [1]]);
+(%o1)              [1, 2, %e, %pi, [1], b + a]
+@end example
+@end deffn
