Description:
------------
i'm often making heavy use of the decorator pattern.
while this works in c++ or java, php tells me the 'protected' context does not work.

how's this to interpret?

Reproduce code:
---------------
<?php

abstract class A {	
	protected abstract function func();
}

class Decorator extends A {

	private $_decorated;
	
	public function __construct(A $a) {
		$this -> _decorated = $a;
	}
	
	protected function func() {
		$this -> _decorated -> func();
	}	
	public function doCall() {
		$this -> func();
	}
	
}

class ASmall extends A {
	protected function func() {
		printf("%s::%s called!\n",__CLASS__,__FUNCTION__);
	}
}

$a = new ASmall();
$dec = new Decorator($a);
$dec -> doCall();

die();

Expected result:
----------------
ASmall::func called!

Actual result:
--------------
<br />
<b>Fatal error</b>:  Call to protected method ASmall::func() from context 'Decorator' in <b>fileName</b> on line <b>12</b><br />
