It strikes me that you could do this by a variation on the theme of a
back_inserter - an adapter which provides an output iterator which inserts
data into the container in the manner you wish. Traversing the queue
requires a variation on the circular iterator theme. And as the two need
shared state (the current "start" location) it could be packaged into an
adapter class of some sort.

Implementing this is, as is traditional, left as an exercise for the reader.
But I'd love to see the results in boost!
