| <p>Super calls along implicit inheritance use the new keyword |
| <strong>tsuper</strong>. While <code>super</code> is still available |
| along regular inheritance, a call <code>tsuper.m()</code> |
| selects the version of <code>m</code> of the corresponding role |
| acquired from the super-team. |

| in the context of role constructors. |
| |
| </p> |
| <p><code>tsuper</code> can only be used to invoke a corresponding |
| version of the enclosing method or constructor, i.e., an expression |
| <code>tsuper.m()</code> may only occur within the method <code>m</code> |
| with both methods having the same signature |
| (see <a href="s2.3.2.b.html" |
| title="§2.3.2.(b) Super in the context of declared lifting" |
| class="sect">§2.3.2.(b)</a> for an exception, where both methods have slightly different signatures). |
