Yeah, the b variable is contained in the E objects and is 
unavoidable, as the E object has to save the region he is at and 
some number has to be reported by the E object to the describing 
objects in case of an action.
The point is, that the slice of numbers, contained in the E 
object is done from nothing. Well, from a void pointer. So, I get 
ordinal numbers from void and not from a list.
Just as the reality (in my head) is: you can count something 
without having written the natural numbers before you start to 
count... Especially, I don't have to create some strange structs 
containing just a number, as I expect to have some millions of 
them.
