In my opinion, this is a much nicer errors package than Go's library, and
I've been using it everywhere:
https://github.com/pkg/errors
Instead of fmt.Errorf("%w"), you do errors.Wrap(err, "message"), and
errors.Unwrap(...) where you want to inspect the error. It's much more
explicit and less error prone.
