yes, but this is no ordinary std::vector. std::vector is for self-contained
value types; boost::ptr_vector is for pointers whose life-time
 must be managed.

| boost::vector<A> vector1, vector2;
| vector1 = vector2;

boost::ptr_vector don't have an assignment operator; it is not Assignable nor 
CopyConstructible.

you must clone or release the container:

vector1 = vector2.clone();
vector1 = vector2.release();
