def main(): li = [8, 8, 5, 1, 1, 1, 3, 3] result = sorted(set(li)) print(result) # [1, 3, 5, 8]	import std.stdio; import std.algorithm; // sort(), uniq() import std.array; // array() void main() { int[] li = [8, 8, 5, 1, 1, 1, 3, 3]; int[] result = li.sort.uniq.array; writeln(result); // [1, 3, 5, 8] writeln(li); // [1, 1, 1, 3, 3, 5, 8, 8] }

Notes:

sort() does 2 things: (1) it sorts the list in-place AND (2) it returns a range over the sorted elements
If you don't want to change the original list, make a copy of it: … = li.dup.sort.uniq.array;
uniq() only works on a sorted input (like the uniq command in Unix: cat file.txt | sort | uniq)
