If you are interested, I'm working on (another) experimental Unix shell: https://github.com/xiaq/das https://github.com/xiaq/das It's still in the stage of design (even the name is not actually decided!), but I've implemented a few components here and there, most notably syntax highlighting, tab completions for file names, running external programs and pipelines for external programs. I will announce it when I personally use it day to day. :)
