  30.         Lazy statements? Sure. There are lazy versions of the C++ statements we all
    31. 

  31.         know and love. For example:
    32. 

  32.       </p>
    33. 

  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. 

  34. <span class="special">[</span>
    35. 

  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. 

  36. <span class="special">]</span>
    37. 

  37. </pre>
    38. 

  38. <p>
    39. 

  39.         Say, for example, we wish to print all the elements that are greater than
    40. 

  40.         5 (separated by a comma) in a vector. Here's how we write it:
    41. 

  41.       </p>
    42. 

  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. 

  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. 

  44.     <span class="special">[</span>
    45. 

  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>
