Example:

...
class Example(T : Drawable) : Drawable {

	T[hash_t] pObjectsToDraw;

	uint pFrom, pTo;

	void setLimit(from, to) {
		pFrom = from;
		pTo = to;
	}

	void remove(T objToRemove) {
		pObjectsToDraw.remove(objToRemove.toHash());
	}

	override void draw() {
		for (uint i = pFrom; i < pTo; i++) {
			pOjectsToDraw[i].draw(); // cannot call
because pObjectsToDraw is an associative and no static or dynamic
array
		}
	}

}
