| <p>Only two substitutions are considered for determining |
| team identity: |
| |
| </p> |
| <ol> |
| <li> |
| For type checking the application of team methods, |
| <code>this</code> is <strong>substituted</strong> by the actual call target. |
| For role methods a reference of the form <code><em>Outer</em>.this</code> |
| is substituted by the enclosing instance of the call target. |
| |
| </li> |
| <li>Assignments from a <code>final</code> identifier |
| to another <code>final</code> identifier are transitively |
| followed, i.e., if <code>t1, t2</code> are final, |
| after an assignment <code>t1=t2</code> |
| the types <code>R<@t1></code> and <code>R<@t2></code> are considered |
| identical. Otherwise <code>R<@t1></code> and <code>R<@t2></code> |
| are incommensurable.<br /> |
| Attaching an actual parameter to a formal parameter in a |
| method call is also considered as an assignment with respect to |
| this rule. |
