The example you are referring to in the "About Proxies" section is a
digression about how the lazy-loading inheritance-proxy pattern could
be achieved on top of the lazy-loading state-proxy pattern implemented
by this RFC, but it doesn't represent the main use-case.
To proxy a final class with this RFC, you can simply call the
newLazyProxy method:
final class MyClass {
public $a;
}
$reflector = new ReflectionClass(MyClass::class);
$obj = $reflector->newLazyProxy(function () {
return new MyClass();
});
Best Regards,
Arnaud
