I don't think you need to really get out of your way to crash python. For
someone discovering __getattr__ for the first time and wanting to do some
simple delegation ...

class A:
    def __init__(self):
        self.a=[]
    def __getattr__(self,key):
        if hasattr(self.a,key):
            return getattr(self.a,key)
        else:
            return getattr(self,key)

Wrong but not really bizzare IMO
