Well, what are you trying to do?

Holy cow, lucky me I don't think like that as I have 100+ zsh
to (if so) translate into Elisp ... [1]

I don't think it is a matter of Elisp being less or more wordy
(but interestingly Elisp and Lisp in general is very wordy
while shell script languages and zsh in particular has
a syntax that is extremely compact and cryptic) - so while it
isn't about that (here), it is rather about where you are and
what you do. Elisp for editing files and inputting text and
shell languages for all work in/from the filesystem.

You can't, and even if it you could, it isn't a good idea
because different languages are intended for different types
of programming tasks.

So while you _can_ hammer a nail with the flip side of the axe
propose a dispose of hammers in any wood shop/carpentry with
this argument and ... no one will do it.

It isn't ...

You are aware that there are other shells than Bash?

Also, shell programming doesn't rely on functions half as much
as does well, functional programming like Lisp.

Shell programming is supposed to be just the glow and binaries
are supposed to do the main job. Nowadays little by little
they have added so much features so a lot more is now possible
with just the shell, but still.
