Support writeable object shape

[momala454]

Apparently, to be able to make properties writeable, you must combine the object shape with stdclass (ref : phpstan/phpstan#10079)
However, it is not supported

Could not parse the type `\stdClass&object{info: string}` that should be mapped: Invalid intersection member `object`, it must be a class name or an interface name

(new \CuyZ\Valinor\MapperBuilder())
    ->allowSuperfluousKeys()
    ->allowPermissiveTypes()
    ->mapper()
    ->map(
        '\stdClass&object{info: string}',
        \CuyZ\Valinor\Mapper\Source\Source::json($string),
    );

sorry I forgot you don't support object (#564 (reply in thread))
Is there any possibility to support objects ?
