## #19482 — Derick Rethans — 2005-10-07T20:29:51+00:00

Hello,

attached is a patch (by Markus) that allows you to make typehints 
optionally take `NULL` as default value too, f.e.:

class P { }
class T {
    function f(P $p = NULL) {
        var_dump($p);
    }
}

$o=new T();
$o->f(new P);
$o->f(NULL);
$o->f();

I would like to commit this patch to HEAD pending any objections.

regards,
Derick
