digitalmars.D - foreach for self-defined data-structure?

↑ ↓ ← → Michiel <nomail please.com> writes:
I'm slowly working on a complete Set class. It would be good if I could
do this:

auto x = Set!(int);
foreach (element ; x) { ... }

Is there a way for me to define foreach for my own class? If not, maybe
there should be.

Correction, I of course meant:

auto x = new Set!(int);
