| If a callin method declares a type parameter <code><T></code> for |
| capturing a covariant return type |
| this type <code>T</code> |
| can be used for specifying the type of exactly one parameter or the return type. |
| If a type parameter is used in more than one position of a <code>callin</code> method |
| it is not considered a <em>fresh type parameter</em> |
| and can thus not be bound to a covariant return type (see <a href="s4.10.d.html" title="§4.10.(d) Binding to a type parameter" |
| class="sect">§4.10.(d)</a>). |
