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.
