- Prefer collections.abc (new in Python 3.3) over collections for abstract base classes

- In Python 3.8, the abstract base classes in collections.abc will no longer be exposed in
  the regular collections module. This will help create a clearer distinction between
  the concrete classes and the abstract base classes."

- https://docs.python.org/3.7/whatsnew/3.7.html#deprecated

- see https://github.com/python/cpython/commit/c66f9f8d3909f588c251957d499599a1680e2320
