At the moment there's a huge number of interactive shells like nushell and xonsh being built, but they don't really focus on scripting; I'd really love to see more competitors attempting to take on the mess of bash scripts.

Check out http://www.oilshell.org/ -- that is exactly its purpose. It runs your bash scripts, and then you can upgrade gradually to a better language.

It's also an interactive shell, but I concentrate on the language first.
