-One downside of this approach is that if you want to add `SpaceStation` as
-a sub-class of `SpaceObject`, and handle its collisions with other
-`SpaceObject`s, you need to:
-
-* Implement all `collide_with` methods for this new class.
-* Add a new virtual method `collide_with(SpaceStation&)` and implement it on

 ## Multiple dispatch on a closed class hierarchy
 
 When even double dispatch is not enough, there is a way to do multiple dispatch
