If I do something like

#include <boost/asio/ip/address.hpp>
#include <boost/network.hpp>

then compilation fails because the references to things like asio::io_service in cpp-netlib resolve to the boost::asio namespace (since the code is in the boost::network namespace).

While I can just reorder the headers, this is still not an ideal situation. Presumably, this could be solved by using absolute references, like ::asio::io_service.
