*rmartin Feb 2021
AttrDict finally broke with Python 3.10 since abstract base classes can no
longer be imported from collections but should use collections.abc instead.
Since AttrDict is abandoned, I've consolidated the code here for future use.
AttrMap and AttrDefault are left for posterity but commented out.

from abc import ABCMeta
from abc import abstractmethod
from re import match as re_match

try:  # python 3

@dwsmith1983 I pushed an update of the deps in #28 and tested locally with python 3.10. It seems to work... Let's see.

@zifeo it happens during build. Did you test building locally on 3.10? Also, strange it just started to occur now when it was fine for the previous releases

[zifeo]

@dwsmith1983 yes, I can even publish without issue. I will investigate, this is curious

Root issue looks to be python-poetry/poetry#1733, downgrading to 3.8 or 3.9 should do the job.

I have also ran into this issue and decided to fix this and release it on PyPI as AttrDict3. Feel free to use it or open issues on the forked repository. After install, you should not have to modify anything in your code-base.
