There's already a plethora of shells that fit that domain: + Nu Shell + NGS + Powershell + Oil Shell + Elvish + Murex (which is one I'd written) Not to mention all the LISP, Python, and other such high level language REPLs come shells. But they solve a different problem. This seems to be more like what Typescript is to Javascript: a alternative "safer" language where your end point is limited to supporting a different language. So you need to compile down to a known portable base language.
