The Wangview code is meant to function as documentation, and as a reference implementation to be ported. Python is beginning to support type hints (although mypy doesn't fully support variable annotations as of 0.501). I think type hints would be valuable for people trying to understand Wangview's algorithms. Wangview shouldn't require the latest Python 3 update to run, so it might be best to keep the type hints in a stubs file.
