I'm sure I'm being a bit dense here, but apart from handling native arrays what does boost::swap give
you that std::swap doesn't?

Extensibility. You call the qualified boost::swap but you can have implementations of swap in a namespace along with the swapee (is that a word?!). This facility is hugely useful when creating your own types and libraries for which you desire swap support. Users that call boost::swap will automatically leverage your customized swap behaviour.
