--- Comment #3 from Seb <greensunny12 at gmail.com> ---
We have group and filter, e.g.

---
import std.stdio;
void main() {
    import std.algorithm;
    immutable data = [10, 3, 2, 3, 4, 10];
    assert(data.dup.sort.release.group.map!(a => a[0]).equal([2, 3, 4, 10]));
}

Closing as WORKSFORME. Plese reopen if you feel that filter and group don't
work for or you have more arguments or examples.
