Now you can not use $this

       class foo {
            public function bar() {
                return function() use ($this) {  // PHP Fatal error:

Cannot use $this as lexical variable

                }
            }
       }

so you have to write:

            class foo {
            public function bar() {
                $obj = $this;
                return function() use ($obj) {
                }
            }
       }

thanks

Correct me if I am wrong, but this is possible in 5.4 with the Closure::bindTo() API, as well as the implied binding of $this. Working in my code: class ServiceLocator {

    protected $services = array();

    public function __construct()
    {
        $this->services['DbAdapter'] = function () {
            return new DbAdapter(
                $this->get('Configuration')['db']
            );
        };
        $this->services['UserTable'] = function () {
            return new TableGateway(
                'user',
                $this->get('DbAdapter')
            );
        };
    }
    public function get($name) {
