Read again. The OP tries to delegate attribute lookup to an (existing) attribute.
IMO the root cause of the problem is that pickle looks up __dunder__ methods in the instance rather than the class.
The recursion comes from the attempted lookup of self.item, when __init__ hasn't been called.
Indeed, and this is what the OP missed. With a class like this, it is necessary to *make* it pickleable, since the pickle protocol doesn't call __init__. --David
