| <p>A role in a nested team may qualify the keyword <code>tsuper</code> (see <a href="s1.3.1.f.html" title="§1.3.1.(f) tsuper" class="sect">§1.3.1.(f)</a> above) by a type name |
| in order to select among different implicit super classes. |
| A term <code>OuterTeam.tsuper</code> evaluates to a corresponding implicit super class |
| within the context of the explicit super-class (here: <code>SuperOuter</code>) of the enclosing team "<code>OuterTeam</code>". |
| A method call <code>OuterTeam.tsuper.m()</code> |
| evaluates to the method version within <code>SuperOuter</code> that best corresponds to the current method containing the tsuper-call. |

| <div class="codecomment"> |
| <ul> |
| <li>In the above example (<a href="s1.html#l1.5" class="listing">Listing 1.5</a>) line 28 selects the method version |
| within the superclass of <code>RoleAndTeamSub</code> (i.e., within <code>RoleAndTeam</code>), |
| resolving to <code>OuterTeam.RoleAndTeam.InnerRole.foo()</code>. |
| </li> |
| <li>Line 29 selects a corresponding method from the context of <code>SuperOuter</code> resolving to <code>SuperOuter.RoleAndTeamSub.InnerRole.foo()</code> |
| which has the same semantics as an unqualified <code>tsuper</code> call would have. |
