<p>The following class satisfies the requirements of a static visitor

of several types (i.e., explicitly: <code class="computeroutput">int</code> and

<code class="computeroutput">std::string</code>; or, e.g., implicitly: <code class="computeroutput">short</code> and

<p>Another example is the following class, whose function-call

operator is a member template, allowing it to operate on values of many

types. Thus, the following class is a visitor of any type that supports

||
streaming output (e.g., <code class="computeroutput">int</code>, <code class="computeroutput">double</code>,

<code class="computeroutput">std::string</code>, etc.):</p>
