You need `"$@"`, not just `$@` at the end of the command. Otherwise it will split any arguments that have spaces in them. E.g. try

    long_fn() {
      echo "$1"
      sleep "$2"
    }

    to 1s long_fn "This has spaces in it" 5

My bad on that typo. I write "$@" so often in shell scripts that I should know better. Also would've been caught by shellcheck. Outside the hn edit window though, so my mistake is permanent :(
