Seems right

Looks good to me. Thank you!

We have the same issue with __get / __set / __isset:

#[AllowDynamicProperties]
class C {
    public $_;
    public function __set($name, $value)
    {
        var_dump(__METHOD__);
        $this->$name = $value * 2;
    }
}

$rc = new ReflectionClass(C::class);

$obj = $rc->newLazyProxy(function () {
    echo "init\n";
    return new C;
});

function foo(C $c) {
    $c->prop = 1;
    var_dump($c->prop);
}

foo($obj);

string(8) "C::__set"
init
string(8) "C::__set"
int(4)

In this case we may need to set the property guard on the real instance before forwarding to it. I will take care of this.

Ah, I missed that one. Thanks!
