i dont think this is a good idea:

if your wrap a wrapper around a wrapper, you will make it
less readable and even more worse: you will confuse a static
checker like shellcheck.

dont see the checker like a "endmonster" you are fighting against.
so this means, even if we loose the 1-liner-contest:

[ -n "$TOPDIR" ] && {
  cd "$TOPDIR" || errorhandler
}
