-------------------------------+--------------------
I have a class `A` which implements `__str__()` and is decorated with
`@python_2_unicode_compatible`.
I have sub-class of `A`, `B`, and `B` 's implementation of `__str__()`
calls `super().__str__()`.
When I call `b.__str__()`, I get the following error: `RuntimeError:
maximum recursion depth exceeded while calling a Python object`.
Partial traceback:
{{{#!python
File "/home/josh/Desktop/temp/djtest/local/lib/python2.7/site-
packages/django/utils/encoding.py", line 42, in <lambda>
klass.__str__ = lambda self: self.__unicode__().encode('utf-8')
File "recursion.py", line 27, in __str__
super().__str__(),

The docs
(https://docs.djangoproject.com/en/dev/ref/utils/#django.utils.encoding.python_2_unicode_compatible)
imply that the decorator should be applied to *any* class implementing
`__str__()`
