In this configuration file, I've discovered the
#' operator, which I did not know, used as:
(add-hook 'LaTeX-mode-hook #'flyspell-mode)
I'm wondering what is the difference with writing just
(add-hook 'LaTeX-mode-hook 'flyspell-mode)
The only documentation I could find about this
#' operator hints that it may have some effect when the code is byte-compiled, but I don't understand how. Is there any difference in this case? If yes, how can I observe it?
