Dependency namedlist incompatible with Python 3.8

[jayvdb]

See #426 (comment)

I've also encountered the same in openSUSE Tumbleweed which has switched to 3.8

https://bitbucket.org/ericvsmith/namedlist/ hasnt been updated for a while.

https://bitbucket.org/ericvsmith/namedlist/pull-requests/4/fix-ast-related-error-with-respect-to/diff is the fix

It is also a HG repo on Bitbucket which means it will be deleted soon.

@ericvsmith, will this be fixed, or should an alternative be found?

I'd suggest switching to dataclasses. I wrote namedlist before I wrote dataclasses, and I can't think of a reason to prefer namedlist. I'm no longer interested in python 2 support enough just to maintain namedlist. dataclasses is supported (via a PyPI project) back to 3.6.

But thanks for the reminder. I really need to move this project to git and make a note that it's no longer supported.
