It’s interesting to note that while no single idea is revolutionary, the design choices in putting together this bunch make for a particularly slick interface where the whole is much better than the usual shell.

PS: I look forward to trying this out! Since I don’t know much Common Lisp, are there particularly useful libraries that would make it easy to cover functionality commonly used through the shell? I’d love to see a tutorial with a compilation of examples. EDIT: Found some useful stuff in the CL cookbook (Eg. section on files & directories) https://lispcookbook.github.io/cl-cookbook/
