Elisp now alows comments without ;.

(setq emacs-lisp-allow-literal-comments nil)
(setq byte-compile-allow-literal-comments nil)

(message "Hello, World!")

It is of course possible to intertwene code
with comments anywhere in the file.

(message "Hello Again!")

Of course we can also comment-out code
just as before:

;;(message "I am silent")
In code blocs the ';' is still a comment delimiter:
(message
 ;; Here is a line commne
 "I am a bit chatty today!")

That's it for today folks!

(message "Bye bye cruel world!")
