I'm not sure what the best solution is here, it's just I had something 
that worked and now I can't get emacs27 to work usefully in the same way.

It should be possible to run the code in the client or a new instance, 
but I didn't manage to get this working.

CODE='(progn (message "HELLO WOLD"))'
emacsclient --eval "$CODE" --alternate-editor  "emacs --eval '$CODE'"

Instead of starting a new emacs and printing HELLO WOLD,
it reports:

emacsclient: error executing alternate editor "emacs --eval '(progn 
(message "HELLO WORLD"))'"
