The Cool New Features in Python 3.8 lists some of the things that could become part of The Modern Python Cookbook 2e. I'm working with Packt on a plan for creating a new edition focused on Python 3.8 features, and using mypy to validate the type hints.

I'm learning a lot about my previously sketchy designs and potential problems with some of them. There are a number of things in Python which "work" in a vague hand-wavey way. But they don't work in a "I can convince mypy this will work" way. 

The additional "convince mypy" rigor can separate potentially sketchy design from an unassailable design.
