Thanx, Simen! I've made the solution myself. Maybe if anyone is interested I
can post it. Though your sampe is good, I've got more complicated thing:

interface Stack(T) {

	void push(T element);

	T pop();

	int isEmpty();
}

class StackImpl(T) : Stack!(T) {

	private T[] data;

	this() {
	}

	public void push(T element) {
		...
	}

	public T pop() {
		...
	}

	public int isEmpty() {
		...
	}

}

void main() {
         Stack!(char) data = new StackImpl!(char)();
}

Seems to work... :)

Example:
IList(T)

A list of elements of type T. Implementations could be LinkedList(T) and 
ArrayList(T).
