| // A friend of a class is a function or class that is given permission to use |
| // the private and protected member names from the class. A class specifies |
| // its friends, if any, by way of friend declarations. Such declarations give |
| // special access rights to the friends, but they do not make the nominated |
| // friends members of the befriending class. |
| // |
| // FIXME: Add tests for access control when implemented. Currently we only test |
| // for parsing. |
