| <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="§4.9.3.(b) Capturing covariant base methods" |
| class="sect">§4.9.3.(b)</a>). |
