The corresponding D version would be:
auto a = [5, 3, 5, 6, 8].uniq.map!(x => x.to!(string)).array.sort.array;
writeln(a);
I'm guessing that's three allocations. But that doesn't even work, it
prints:
["3", "5", "5", "6", "8"]
uniq needs sorted input:
auto r = [5, 3, 5, 6, 8].sort.uniq.map!(x => x.to!string);
writeln(r);
Tested with dmd 2.059.
I think the above should be one allocation (except for the strings).
Maybe uniq should require a SortedRange?
Yes, please file a bug. Thanks!

Actually I take that back. One may use uniq to remove duplicates in
unsorted ranges.
