Chi is amazing. I love the philosophy of extending the stdlib instead of writing an alternative. I try to keep that in mind when writing my own libs or helpers now, and I'm very satisfied with the results.
For example I made a lib to write commands (like cobra or urfave/cli), but based entirely on the `flag` package: https://github.com/Thiht/go-command
