 New Comment:

There was lots of discussion about this, because it could override
class methods like:

class Test { 
  private $closure;

  public function __construct() {
    $this->closure = function() {
      echo 'Hello World';
    };
  }

  public function closure() {
    echo 'Hello PHP';
  }

  public function call() {
    $this->closure();
  }
}

$test = new Test;

// Call Test::$closure or Test::closure() now?
$test->call();


What you need to do is to copy the instance into a variable like:
$closoure = $this->closure;
$closure();

Description:
------------
Placing a class with an __invoke method as a property inside another 
class seems to nullify the invokeability of the original class.

Tested on:
Ubuntu 9.04, PHP 5.3.0
CentOS 5.3, PHP 5.2.11 ionCube / Suhosin

Reproduce code:
---------------
class a { 
  function __construct() { } 
  function __invoke() { echo("Invoked\n"); } 
} 

$a = new a(); 
$a(); 
// Prints: Invoked 

class b { 
  private $x; 

  function __construct() { 
    $this->x = new a(); 
    $this->x(); 
  } 
} 

$b = new b(); 
// Issues error: undefined method b::x  

Expected result:
----------------
I expect "new b()" construct to call the class a invoke

Actual result:
--------------
Undefined method - it doesn't seem to recognise the invokeable class 
property as actually invokeable.
