Subject: Re: [PHP-DEV] [PATCH] [RFC] Closures and lambda functions in PHP
From: kalle@php.net (Kalle Sommer Nielsen)

Hey

How are we going to deal with Closures in class properties, like:

class PHP
{
	public $closure;

	public function __construct($callback)
	{
		$this->closure = $callback;
	}

	public function closure()
	{
		echo 'PHP::closure';
	}
}

$closure = function()
{
	echo 'PHP::$closure';
};

$test = new PHP;


Now calling $closure->closure(); whats going to happen? I would assume it
executes the method first if and if there aren't a method with the name it
will execute the $closure property?


Another subject I would like to see now the closures has been brought up again
is, how about adding type hinting in method/function prototypes:

function call(function $callback)
{
	$callback();
}

call(function(){ echo 'Hello'; });

We could make reuse of the function keyword in the prototypes which saves us
from adding another keyword to the language.


Cheers,
Kalle
