// boost::swap internally does an unqualified function call to swap.
// This could have led to ambiguity or infinite recursion, when the
// objects to be swapped would themselves be from the boost namespace.
// If so, boost::swap itself might be found by argument dependent lookup.
// The implementation of boost::swap resolves this issue by giving
// boost::swap two template argumetns, thereby making it less specialized
// than std::swap.
