Instead of my usual Twitter and Fediverse threads, for this release of cattrs I

By properly utilizing Algebraic Data Types (ADTs, not to be confused with

runtime errors into type-checking errors, making them an excellent
Everyone doing Python nowadays is aware Python supports optional type hints, and
has for some time now. This has created a small schism in the community, with
some people being completely uninterested in
