Sure it works ! :)



import std.stdio;


class Foo {
	int[] data;

	struct Iter_each {
		Foo owner;
		void opIn(void delegate(int) dg) {
			foreach (int d; owner.data) {
				dg(d);
			}
		}
	}

	Iter_each each() {
		Iter_each res;
		res.owner = this;
		return res;
	}
}



void main() {
	Foo foo = new Foo;
	foo.data = [34, 2, 55, 23];

	foo.each in (int i) {
		writefln(i);
	};
}
