<p>End the current block body and start a new one. <a href="header.html">Headers</a> (<code><span class='Head'>:</span></code>) and <a href="predicate.html">predicates</a> (<code><span class='Head'>?</span></code>) can control which body is evaluated. A function can have two headers without these, indicating the monadic and dyadic cases.</p>
