 New Comment:

you don't need always use :: to call static method,  actually,  :: doesn't means 
calling static method all the time.

you could use $this->speaker->say($str).

anyway, I agree we can do some improvement here, assign to myself. I can solve 
this in the mean time of implement the instance function call FR

thanks

Update the package — I'm pretty sure this is a limitation of the parser that isn't
likely to be fixed any time soon, but hopefully one of the guys who works on the parser can confirm
that.

Description:
------------
Calling a static method on an instance of class which is member of another class 
results in parse error.

Test script:
---------------
class Speaker
{
	public static function say($str) { echo $str; }
}

$speaker = new Speaker();
$speaker::say('This works');


class failingToCallSpeaker
{
	private $speaker;
	
	public function __construct(Speaker $s)
	{
		$this->speaker = $s;
	}
	
	public function doesntWork($str)
	{
		$this->speaker::say($str);
		// PHP Parse error:  syntax error, unexpected '::' (T_PAAMAYIM_NEKUDOTAYIM) 
	}
	
	public function works($str)
	{
		$s = & $this->speaker;
		$s::say($str);
	}
}

$dontwork = new failingToCallSpeaker($speaker);
$dontwork->works('hurray');
$dontwork->doesntWork('argh');

Expected result:
----------------
PHP Parse error:  syntax error, unexpected '::' (T_PAAMAYIM_NEKUDOTAYIM) on line 

$this->speaker::say($str);
