// Tests whether two object in a namespace other than boost are properly
// swapped, when both boost and the other namespace have a custom swap function
// for their class. Note that it shouldn't be necessary for a class in an other
// namespace to have a custom swap function in boost, because the boost::swap
// utility should find the swap function in the other namespace, by argument
// dependent lookup (ADL). Unfortunately ADL isn't fully implemented by some
// specific compilers, including Intel C++ 8.1, MSVC 7.1, and Borland 5.9.3.
// Users of those compilers might consider adding a swap overload to the boost
// namespace.
