Steps to Reproduce

pip install the following:

# This will cause a failure.

Create the following files:

conf.py :

extensions = ['sphinx.ext.autodoc', 'enum_tools.autoenum']

index.rst :

.. autoenum:: enum_tools.demo.People
    :members:

My guess is that this is a combination of errors, and the particular UnboundLocalError from https://github.com/sphinx-doc/sphinx/blob/6183b6abee561fc71c88fc66416d31a8f8ca009f/sphinx/ext/autodoc/__init__.py#L775-L777 is a Sphinx error.
