oopps. sorry i was too fast writting this. i meant nounset option.
i want my shell to yell at me as soon as i do something wrong so
my ~/.zshenv starts with

    setopt warncreateglobal nounset pipefail

Thanks for the feedback! As always, i think everyone comes with cultural
biases when it comes to coding style.  when i read

    case "$var" in
        (a*) write ;;
        (b*) something ;;
        (c*) cool ;;
    esac

i would like to see/write

    # in raku
    given $var {
        when /a*/ { write }
        when /b*/ { something }
        when /c*/ { cool }
    }

    # in rc

    switch ($var) {
        case a* ; write
        case b* ; something
        case c* ; cool
    }

and i used to actually read/write

    # zsh

    case "$var" {
        (a*) write
        ;;
        (b*) something
        ;;
        (c*) cool
        ;;
    }

because i though for many years that alternative syntax will replace the
old one the way zshcompsys replaced zshcompctl. but:

* it will never happen and i have to fall back with the classic syntax
  whenever i contribute to existing codebases.
* i started replace zsh by dash or rc in my scripts whenever the
  awesomeness of zsh doesn't help a lot (which means "lot of them")

so now i try to stick to POSIX syntax whenever it's easy to do it but i
try to adapt the coding style so the code keep staying attractive to me.

indeed. what i just did is to remove a "useless new line".

        ...
        some code
        there
    ;;
    (newcase)

and
        ...
        some code
        there
    ;; (newcase)

both to me and the interpreter and the second one looks much more
natural to me. i'm not trying to convince anyone. i was really please to
read your feedback so i try to share my opinion on it.
