The main thing is that it will be an entirely new programming language that you can convert bash scripts to. That's why I went to the trouble of writing a pretty complete bash parser as well as an executor. I mention that on the blog, but I haven't written about it a lot since I haven't implemented the language yet. It's designed with a big doc but not implemented yet. Have you ever written a completion function in bash? IMO it's kind of a nightmare. That should be one of the initial use cases for a better language. It would be closer to writing it in Python or ES6 rather than bash. If you just wanted to use sh syntax, then the reason you would use it is because it will have better parse errors and better runtime errors, which I talk about on my blog. But right now I don't actually expect anyone to use it, because it's in the early stages, like I say.
