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

Inizia da mautrix/types/util/obj.py, in particolare da getattr e serialize(), e riproduci l’esempio inspect.unwrap(mautrix.types.Obj()) dell’issue. Verifica che i nomi dunder o sunder mancanti non vengano creati dinamicamente, mentre gli attributi normali mancanti mantengano il comportamento esistente. Il lavoro è completato quando l’esempio non lascia più l’oggetto serializzabile ricorsivamente e solleva solo l’errore di unwrap previsto.

>>> import mautrix.types

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.
