Import collection ABCs from collections.abc

DeprecationWarning: Using or importing the ABCs from 'collections' instead of from 'collections.abc' is deprecated since Python 3.3, and in 3.9 it will stop working

Um, OrderedDict isn't in collections.abc in any version of Python? Look at https://github.com/python/cpython/blob/3.9/Lib/_collections_abc.py for the Python 3.9 version of collections.abc?

Uhh. Whoops. I definitely wasn't paying enough attention to what I was doing, apparently I was using version 1.0.1 of html5lib when I got that warning and it was for Mapping, not OrderedDict, but that's been fixed already.
Closing.
