title: Autoloader for functions
body: <p>Last week I learned that classes can be included in your project by writing an <code>__autoload()</code> function. Then I learned that using an autoloader isn't only a technique but also a pattern.</p>
  
  <p>Now I'm using the autoloader in my project and I've found it very very useful. I was wondering if it could be possible to do the same thing with functions. It could be very useful to forget about including the right PHP file with functions inside it. </p>
  
  <p>So, is it possible to create a function autoloader?</p>
