Sadly I will only be able to get the paper next year.

That needs a bit more explanation :)

We could easily deep copy it when it only referenced them, because the object graph would contain exactly the objects it needed to work in every world, without taking the entire world with it. It wouldn't know about the others anyway.
>> I like the way mixins are used, you have to explicitly demand them. Other objects and especially prototypes should be handled the same way. You reference them explicitly only if you need them, say in a "import*" parent object (if you don't want them to mess your object) and not via the lobby by name. Since slots are created in the context of the lobby you could easily add a slot and do "gasTank = gasTank"
