Indeed. However you can achieve things like that in an ordinary Lisp via unevaled (special) forms, with other words, macros. In Emacs Lisp eshell does it too, though they have extra advantage since Emacs has built-in text editor and text processing extensions. Eshell implements both Bash and Lisp syntax. I am not sure if "sharp lisp" does anything special for scripting than any other Lisp, but it is possible to do.

That's true but when you do that it's not really lisp anymore it's another language you just created and implemented as a lisp macro.

Indeed; that is my objection to the loop and format in CL.

But on the pragmatic side, if you want to interop with shell, or some other language/runtime, isn't it sometimes easier and less typing and noise if a program can be expressed in DSL or as a mix of Lisp and a DSL than if everything is written in pure s-expressions?
