Seems like ast on Python 3.9 changed a bit.

To Reproduce
I don't know if it's a particular expression/annotation that triggers this, or just a general error due to changes in ast. Needs investigation (first, read Python 3.9 changelog for ast).

Expected behavior
No exception.

System (please complete the following information):

• pytkdocs version 0.9.0
• Python version: 3.9.0
• OS: Linux

This could be due to https://bugs.python.org/issue40430 . Something similar to best-doctor/flake8-annotations-complexity#5

[pawamoy]

Thanks for the links @tirkarthi! It does look like a legitimate change in ast. This is really annoying so I'll try to fix this ASAP.

Should be fixed in 0.10.1.
