Re: The Hack language : PHP avec un peu de typage statique ?

Voici la complexité d'un proxy naïf :

<?php
class proxy
{
 private $targets = array();
 public function __construct(array $targets = array())
 {
 $this->targets = $targets;
 }
 public function __call($method_name, $args)
 {
 foreach($this->targets as $target)
 if(method_exists($target, $method_name))
 return call_user_func_array($target, $method_name);
 throw new exception(sprintf('Method \'%s\' doesn\'t exist', $method_name));
 }
}
class first
{
 public function first()
 {
 return 'first';
 }
}
class second
{
 protected function second()
 {
 return 'second';
 }
}
$proxy = new proxy(array(new first, new second, new third));
assert('first' === $proxy->first());
try
{
 $proxy->third();
 assert(false);
}
catch(exception $e) { }
$proxy->second(); // This trigger a fatal error
assert(false);
