I'm dusting off a Rust project from 2016, and it's striking how much the ecosystem has grown. For example, I used getopts then whereas clap is delightful and does so much now.

zsh is generally wonderful, and it's sufficiently like bash/POSIX sh that it works. However, it uses 1-indexed arrays, whereas bash uses 0-indexed arrays. This totally caught me out.

The bottom type has a different name in a bunch of languages. I've seen nothing, _|_, !, never and empty. I don't know which is the most approachable to users though. `List[Empty]` reads very nicely for an empty list, whereas `never` reads nicely for error functions.
