  Use R ::= Q[x,y,z];
  L := [x,y,z];
  Sorted(L);
[z, y, x]
-------------------------------
  Sorted([y,x,z,x^2]);
[z, y, x, x^2]
-------------------------------
  Sorted([3,1,1,2]);
[1, 1, 2, 3]
-------------------------------
  Sorted([<quotes>b</quotes>,<quotes>c</quotes>,<quotes>a</quotes>]);
[<quotes>a</quotes>, <quotes>b</quotes>, <quotes>c</quotes>]

[Ideal(x), Ideal(x, y)]
