why do you think this code won't compile? As far as I can tell, ADL would resolve the call to invoke std::swap().

Try it. std::swap can't swap arrays, boost::swap can. boost::swap will also call swap via. ADL when appropriate and supports compilers that don't support ADL. Which is why it's recommended that 'boost::swap' is used. Daniel
