Subject: Re: [PHP-DEV] [VOTE] Alternative typehinting syntax for accessors
From: cryptocompress@googlemail.com (Crypto Compress)

Hello Nikita,

for me this "maybe-of-type"-typehinting is a small progression in the right
direction.

But "Default values and nullability" would break existing code as you need
to add a default null at "design-time" (BC break):

<?php
class C {
     public $a; // public string $a = null;
     public $b; // public string $b = null;
     public function __construct($a, $b) {
         $this->a = $a;
         $this->b = $b;
     }
}

// test only a
$c = new C("foo", null);
var_dump($c->a === "foo");

// test only b
$c = new C(null, "foo");
var_dump($c->b === "foo");
?>
