<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&lt;@t1&gt;</code> and <code>R&lt;@t2&gt;</code> are considered
identical. Otherwise <code>R&lt;@t1&gt;</code> and <code>R&lt;@t2&gt;</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.
</li>
</ol>
