I’d love to use a Racket shell and script Unix in a ‘natural’ way. You may wish to read up on scsh. While it was way ahead of its time, Olin Shivers made the syntax as natural as possible so it would be quickly useful to people used to basic shell scripting syntax. After all, this syntax has a 40+ history and shouldn’t be thrown out.
