| <p>It is neither useful nor legal to import a role type.<br /></p> |
| <div class="note"> |
| <h5>Rationale:</h5> |
| Importing a type allows to use the unqualified name in situations that would otherwise require to use the fully qualified |
| name, |
| i.e., the type prefixed with its containing package and enclosing class. Roles, however are contained in a team <i>instance</i>. |
| Outside their team, role types can only be accessed using an anchored type which uses a team instance to qualify the |
| role type. |
| Relative to this team anchor, roles are <i>always</i> denoted using their simple name, which makes importing roles useless. |
| |
| </div> |
| <p>A static import for a constant declared in a role is, however, legal. |
