The Prototype pattern: potential type mismatches

[horw]

Hi, perhaps this example isn't the best one because there's a potential for type mismatches. If we want to use type matching here, perhaps 'switch' is a better choice; or at least I think using the following type checking method would be better.

        t1, ok := c.(*Type1)
	if !ok {
		t.Fatal("error")
	}
