Andy Maier added the comment: Using Ethan's sample code (Thanks!!), I was pointed in the right direction and was able to produce a simple piece of code that reproduces the behavior without depending on enum34, as well as a proposal for a fix in pydoc.py. The problem can be reproduced with a

Terry J. Reedy added the comment: Devise a simple test (fail before, work after) that does not require enum34. If this fix is committed, the message could note that the same issue was fixed differently in 3.4 mixed in with other changes. -- nosy: +terry.reedy stage: - test needed

Ethan Furman added the comment: The problem will affect anything that uses the same mechanism as enum. It also affects (not verified) all versions of python up to 3.4 where it was fixed because enum exposed it. Besides which, I did not think a bug had to affect stdlib code in order to be
