30        Lazy statements? Sure. There are lazy versions of the C++ statements we all
31        know and love. For example:
32      </p>
33<pre class="programlisting"><span class="identifier">if_</span><span class="special">(</span><span class="identifier">arg1</span> <span class="special">&gt;</span> <span class="number">5</span><span class="special">)</span>
34<span class="special">[</span>
35    <span class="identifier">std</span><span class="special">::</span><span class="identifier">cout</span> <span class="special">&lt;&lt;</span> <span class="identifier">arg1</span>
36<span class="special">]</span>
37</pre>
38<p>
39        Say, for example, we wish to print all the elements that are greater than
40        5 (separated by a comma) in a vector. Here's how we write it:
41      </p>
42<pre class="programlisting"><span class="identifier">std</span><span class="special">::</span><span class="identifier">for_each</span><span class="special">(</span><span class="identifier">v</span><span class="special">.</span><span class="identifier">begin</span><span class="special">(),</span> <span class="identifier">v</span><span class="special">.</span><span class="identifier">end</span><span class="special">(),</span>
43    <span class="identifier">if_</span><span class="special">(</span><span class="identifier">arg1</span> <span class="special">&gt;</span> <span class="number">5</span><span class="special">)</span>
44    <span class="special">[</span>
45        <span class="identifier">std</span><span class="special">::</span><span class="identifier">cout</span> <span class="special">&lt;&lt;</span> <span class="identifier">arg1</span> <span class="special">&lt;&lt;</span> <span class="string">", "</span>
46    <span class="special">]</span>
47<span class="special">);</span>
48</pre>
