spl_autoload_register cosa sbaglio?

[zacca94]

index.php

<?php
namespace system\bootstrap;
use system\bootstrap\Blind;
use BaseHandler\BaseHandler2;
use BaseException\ExceptionHandler;
use test\prova\lol;

set_error_handler(array('system\bootstrap\Blind', 'errorHandler'), E_ALL);
spl_autoload_register(array('system\bootstrap\Blind', 'autoload'));

class Blind {  
  public function __construct() {
    //lol::ok();    
    //\test\prova\lol::ok();    
    echo $s;  
  }    

  public static final function autoload($className) {
    $namespaces = explode('\\', $className);    
    $method = array_pop($namespaces);
    include('includes/'.implode('/', $namespaces).'.php');  
  }

  public static final function errorHandler($errorNo, $message, $filename, $lineNo) {     
    throw new ExceptionHandler();  
  }
}

new Blind;

echo $s; mi serve per generare un errore da catchare.

includes/BaseHandler.php

<?php
namespace BaseHandler;

class BaseHandler2 extends \Exception {}

includes/BaseException.php

<?php
namespace BaseHandler;

class ExceptionHandler extends BaseHandler2 implements IException {    
  public function __construct($message = '', $code = 0, $description = '', \Exception $previous = null) {        
    parent::__construct((string) $message, (int) $code, $previous);            
 }        

  public function show() {      
    echo "ok";    
  }
}

Errore:

Fatal error: Cannot redeclare class BaseHandler\BaseHandler2 in \includes\BaseHandler.php on line 6
