Possible addition to Fortran Fshell or Fortshell or Fortran Shell

[iajzenszmi]

Fortran used as a system shell, like Bash, but with fortran language commands, statements,type declarations etc. Interpreted as well as compiled versions.

You can use LFortran interactively, just like that. But you would have to launch commands using Fortran. I assume you want to blend Bash and Fortran? Something like a blend of Bash and Python: https://xon.sh/ ?
