TypeError: argument of type 'AmazonCall' is not iterable
The problem is that AmazonCall.__getattr__ interprets Amazon.__name__ as an Amazon API call instead of raising AttributeError. Pydoc calls __name__ expecting to receive either a string or AttributeError, which leads to the error in the traceback. Perhaps double-underscore methods should be exempt from the special __getattr__ handling.
