@andros@marcolas Web applications use #JavaScript to shoehorn themselves into an environment designed to browse hyperlinked documents.
And “#Emacs applications” (e.g., Org Mode, Gnus, calendar/diary, ERC, and even multiple web browsers!) use #Elisp to shoehorn themselves into an environment designed to edit text documents.
You’re so blinkered by the ubiquity of apps shoehorned inside apps that you’ve forgotten the compromises they introduce.
