container.jam question

I want to write a rule which returns a pair of lists. Looking at 
container.jam, it is not obvious how to do it. Rene, can you suggest 
something -- now it looks like one cannot use ordinary jam lists as elements 
of "list" class. I'd like to be able to:

l = new list ;
$(l). push-back 1 2 3 4 5 ;
$(l).push-back 1 2 3 ;
