Hello,
I have an array of objects of class C which contain a id member.
I want to figure out if all the id members are unique using
functional primitives.
For example, if I have:
class C
{
int id;
}
and an array of C

Or use findAdjacent:
auto idsAreUnique = ids.array.sort.findAdjacent.empty;

@Edwin: Thank you for the insight about indexed range.
@Adrea: Thanks, this looks good. Even if I found it a little
obscure at first sight, it's better than my previous solution.

Hello,
I have an array of objects of class C which contain a id member.
I want to figure out if all the id members are unique using
functional primitives.
For example, if I have:
class C
{
int id;
}
and an array of C 'Cs';
My idea was to do:
auto ids = Cs.map!(c => c.id);
