It seems like \Railt\SDL\IR\Type::null() targeting Railt\SDL\IR\Type\TypeConstructors\RuntimeTypeConstructors::null() can also be of type object<Railt\SDL\IR\Type\TypeConstructors\RuntimeTypeConstructors>; however, Railt\SDL\IR\SymbolTable\Value::__construct() does only seem to accept object<Railt\SDL\IR\Type\TypeInterface>, maybe add an additional type check?
