[Serhiy Storchaka]

New submission from Serhiy Storchaka:

Example:

>>> import socket
>>> x = socket.AddressFamily.from_bytes(b'\1', 'big')
>>> type(x)
<enum 'AddressFamily'>
>>> int(x)
1
>>> str(x)
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/home/serhiy/py/cpython/Lib/enum.py", line 464, in __str__
    return "%s.%s" % (self.__class__.__name__, self._name_)
AttributeError: 'AddressFamily' object has no attribute '_name_'
>>> repr(x)
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/home/serhiy/py/cpython/Lib/enum.py", line 461, in __repr__
    self.__class__.__name__, self._name_, self._value_)
