Elixir and javascript have the capability of making good looking one liners, but what about Ruby? We can definitely make an awful looking one by adding a ';'. If you want to start defining some better looking one-liners then add the 'nicefn' gem to your project. Since the implementation files are small and this project has no required deps. You should also feel free to copy and paste the implementation directly into your project in an effort to avoid extra gems.
