- // 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.
