using inspect.unwrap on `maurix.types.Obj` places the object into a state where serializing raises a RecursionError

Commencez dans mautrix/types/util/obj.py, en particulier avec getattr et serialize(), et reproduisez l’exemple inspect.unwrap(mautrix.types.Obj()) de l’issue. Vérifiez que les noms dunder ou sunder manquants ne sont pas créés dynamiquement, tandis que les attributs normaux manquants conservent leur comportement existant. Le travail est terminé lorsque l’exemple ne laisse plus l’objet sérialisable récursivement et lève uniquement l’erreur unwrap attendue.

RecursionError: maximum recursion depth exceeded

this appears to be caused because inspect.wrapper attempts to access .__wrapped__ which causes the __getattr__ to create it, which is bad.

maybe it would be a good idea not to create __dunder__ and _sunder_ names? so something like:

def __getattr__(self, name):
    if name.startswith("_") and name.endswith("_"):
        raise AttributeError(name)
    ...

just to prevent brainfarts: this wont prevent access to defined dunders since __getattr__ is only called when the name cannot be found through other means.
