<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.
</p>
<p>See <a href="s2.4.2.html"
title="&sect;2.4.2&nbsp;Role creation via a regular constructor"
class="sect">&sect;2.4.2</a> for <code>tsuper</code>
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="&sect;2.3.2.(b)&nbsp;Super in the context of declared lifting"
class="sect">&sect;2.3.2.(b)</a> for an exception, where both methods have slightly different signatures).
</p>
<div class="codecomment">
In <a href="s1.html#l1.3.1-1" class="listing">Listing 1.3.1-1</a> the role <code>R1</code> in team <code>T</code>
overrides the implicitly inherited method <code>m()</code> from <code>S</code>. <code><strong>tsuper</strong>.m()</code> calls the overridden method <code>m()</code>
from <code>S.R1</code> (line 13).
