I've also thought about it some more and think I understand your meaning 
better.
How about using dequeue with an addition member variable, `int 
start_ndx`.  Then
the range would be start_ndx...size()-1.  Boost probably already has

I'll look.   I'll be away from coding for this weekend, but I will 
respond to emails.
