I wasn’t trying to go into typing as much as using structs or objects when working with known data attributes. Sorry that it was a bit misleading.

The original actually went into using trees, sets, heaps, tries, etc., but it felt way too… ranty. After writing all that out, I realized that most of those other cases come up really infrequently, and that my biggest gripe was about not using structs or other pre-defined key container types. I thought it would be better to keep things short and focused.

Maybe I should re-write and publish a data structures edition.

I love the addition of dataclass. Makes refactoring such a breeze. If you need to extract some function, boom, you already have a class that you’re using everywhere.

I’ve used pine64 boards for this. They have a few more options and are always available.
