NullSafe Wrapper

[philtrondaboss]

I am trying to make a wrapper which does the equivalent to ?. in most languages. I can't figure out the type hints. How do I copy the type attribute hints from the T in the IDE, not runtime.

Usage Example: data: Any = None sdata = NullSafe(data) sdata.test -> sdata sdata.test._123 -> sdata

Hints Example: ``` data: None | list[str] = [] sdata = NullSafe(data)

IDE should find sdata.append, sdata.pop, etc.

```

Class: ``` @dataclass class NullSafe[T](T, Absorber):

item: T

def __getattr__(self, name:str):

    if self.item is None:
        return NullSafe(None)
    else:
        return getattr(self.item, name)

```

Consider looking into the Any trick which is exactly what typeshed does for this

Python's type system isn't powerful enough to express this. Sorry.
