[boost] [Range] Composite Range

Is there any facility supported in Boost to provide a 'composite' range? I.e., a range that might be a vector, followed by a bit of list, followed by a pair of iterators? I guess the iterator classification of such a range would be the lowest common denominator of the classifications of all the component iterators, and I don't even want to think about how sort() would work, but it might be quite handy. - Rob.
