| // 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. |
