<span class="keyword">fun</span>&nbsp;_&nbsp;<span class="keywordsign">-&gt;</span>&nbsp;...v...)&nbsp;v&nbsp;</code></li>

<li><code class="code">&nbsp;<span class="keyword">let</span>&nbsp;f&nbsp;=&nbsp;<span class="keyword">fun</span>&nbsp;x&nbsp;<span class="keywordsign">-&gt;</span>&nbsp;...&nbsp;&nbsp;<span class="keyword">let</span>&nbsp;v&nbsp;=&nbsp;...&nbsp;<
