The new version of the urfave/cli library is moving to generics, and it's completely unclear to me why this is an improvement. Their new API is very complicated to understand, which for me, defeats the purpose of golang. In parallel, I needed to do some upcoming cli API refactoring, so this was a good time to look into new libraries. After a review of the landscape, I found the alexflint/go-arg library which has a delightfully elegant API. It does have a few rough edges, but it's otherwise very usable, and I think it would be straightforward to add features and fix issues. Thanks Alex!
