    foreach ($constructorParameters as $name => $value) {
        if ($name == 'this') {
            continue;
        }
        $reflectionProperty = new ReflectionProperty($class, $name);
        $reflectionProperty->setAccessible(true);
        $reflectionProperty->setValue($object, $value);
        $reflectionProperty->setAccessible(false);

}

I don't think it's a good idea - it does not give any clue if you pass parameters of bad types to the constructor, which is helpful while using DI container.

Please do not take this as a solution for production code - it is a proof of concept to see if such a feature build into the language (like in Scala) would make sense.

OK, thanks for explaining.
