<p>The <code>playedBy</code> relation by itself has no effect
on the behavior of role and base objects.
It is, however, the precondition for translation polymorphism
(lowering: <a href="s2.2.html" title="&sect;2.2&nbsp;Lowering" class="sect">&sect;2.2</a> and lifting: <a href="s2.3.html" title="&sect;2.3&nbsp;Lifting" class="sect">&sect;2.3</a>)
and for method bindings (callout: <a href="s3.html" title="&sect;3&nbsp;Callout Binding" class="sect">&sect;3</a> and callin: <a href="s4.html" title="&sect;4&nbsp;Callin Binding" class="sect">&sect;4</a>).
