How do I Type vs Same Type referencing?

I've read the advanced tutorials on events and I'm still kind of not really clear on how to handle say, sprites of the same type/family colliding with each other. The event system narrows down lists within a type or family, but how do you come out with 2 things colliding of the same type?

I do it by having them in 2 different families, but it's awkward. Is there a better way to do it?

You only need one family. Then you compare Family against Sprite.
