Right, it is indeed storing the points because it has to return them. 
Alternatively it can do what you suggest (making the iterator dependant 
on range) or create them on the fly (having to store a reference to the 
box inside, seems OK, it is there already in the form of an address). 
Making the iterator dependant on the range is not a big problem because 
(I think) there is no big need to use it outside.

Did you work out your suggestion in your solution? If so, could you send 
it such that we might replace it?

Thanks, Barend
