[graingert]

also some other dbm things https://github.com/python/cpython/blob/master/Lib/lib2to3/fixes/fix_imports2.py#L7-L8

[benbariteau]

There's a (not finished) PR for one of those. #180

[benbariteau]

If you want me to add more moves, I'm happy to do so, but this is the one I really care about.

[graingert]

I'd like to see a comprehensive PR will all the moves added, but I'm not the maintainer and I believe this package is now unmaintained

The six.moves name should be dbm_ndbm.

[benbariteau]

Should I add the other dbm moves as part of this branch?

[benjaminp]

Which are those?
