Parse error found with Hypothesmith #970

Nice! |
FWIW this is also a bug in upstream lib2to3. You might want to report it on http:https://bugs.python.org/ |

I found this weird little string with
hypothesmith
, a tool for generating Python source code with Hypothesis that I started at the PyCon NA sprints and published at the PyCon AU sprints. Currently it works based on an approximate grammar, post-processing, and filtering.CC @ambv who I know was interested in fuzzing 😄. Next steps... I think a combination of targeted mutation (open PR upstream) and spending more than a few minutes of CPU time could turn up a lot more weird things!
