OK great, glad you have made use of the page. We had an "alternative shells" thread about a year ago between the authors of Elvish, NGS, Oh, and mash. Those were the main active/nascent shells I could find.

It might be time to start that again to see what ideas people have and what has changed. If you're interested e-mail me at [email protected].

I'm also interested in the Shill shell, which as I understand was written in Racket, and then somehow they moved away from Racket? I'm not sure. I think it was because of the runtime. I also saw some efforts to move Racket to Chez Scheme.

I very much like Racket as an idea -- a meta language -- but I haven't gotten a chance to play with it too much.

And I did experiment with femtolisp as a basis for Oil -- the lisp used to bootstrap Julia -- but I decided against it.
