<p>The callin binding also effects instances of any type <code>BSub</code>
that is a sub-type of <code>B</code>.
If <code>BSub</code> overrides the bound base method <code>bm</code>,
the overridden version is generally affected, too.
However, if <code>bm</code> covariantly redefines the return type from its
super version, the callin binding has to explicitly specify if the covariant
sub-class version should be affected, too (see <a href="s4.9.3.b.html"
title="&sect;4.9.3.(b)&nbsp;Capturing covariant base methods"
class="sect">&sect;4.9.3.(b)</a>).
