See http://wiki.php.net/rfc/closures/object-extension
; binding the
closure scope to the scope of where it's declared is already implemented
in trunk.

Description:
------------
It doesn't make sense that closures declared inside methods are run with
global context instead of the same context as the method. This is
incredibly annoying as it there are no way to reference
private/protected functions in closures. It's not possible to acquire a
reference to the private/protected functions and pass them to the
closure either so you're locked out from a developers perspective.
See test script.
The fix should be simple. Just inherit the access-context when closures
are declared...
Test script:
---------------
class Foo {
private function bar($a, $b) {
return $a + $b;
}
public function baz($c) {
$biz_fn = function($c) {
return Foo::bar(5, 4) - $c;
};
return $biz_fn($c);
}
}
$foo = new Foo();
echo $foo->baz(3);
Expected result:
----------------
"6"
Actual result:
--------------
Fatal error: Call to private method Foo::bar() from context '' in..
