Note also that what it returns is not an array, but a lazily

arr.sort();
arr = arr.uniq.array();

Out of curiosity, if the requirement was to *also* preserve
ordering (eg: remove all non-first elements), how would you go at
it?
[2, 1, 1, 3, 2, 3] => [2, 1, 3];
Maybe std.algorithm's `makeIndex` would help here?
Bonus points for doing it inplace.
