I love how the CommonMark Spec has a test suite that's just a JSON array. It's really easy to test a library for compliance, and I've seen developers nerd-sniped into full compliance. https://spec.commonmark.org/0.31.2/spec.json

Trying the nix CLI today, and I'm seriously impressed with the formatting of its --help output. Indented warnings, italics, bullets, even adding a left border to code snippets! It's a nice reminder to take full advantage of terminal features to help the reader.

I've heard of 'blub languages', where you don't realise that other languages have better abstractions until you've experienced them. I think the same thing happens with individual features. I've seen several C++ folks miss variadic generics in Rust, but I've not written enough C++ to feel it.
