DEPRECATED Actually this was the second variant of the second attempt. Originally I named the macro f and quite liked it because the terminal of f connects nicely with the quote: f'something. Unfortunately I could not use that name because I was told that as a deputy maintainer of Melpa, I should lead by example and not use a name that conflicts with an existing package. (Was planning to ask the maintainer of f to donate the symbol f.) l'something is visually much less appealing so I went back to the drawing board and ultimately decided, that my original approach was best after all.

Compact syntax for short lambda.

After llama, this is my second attempt at providing such syntax without having the power to add actual new syntax to Emacs, which means that I have to fake it, which means that compromises cannot be avoided.

The l macro allows you to write one of these three expressions:

(l`list % %2 %*)
(l'list % %2 %*)
(l list % %2 %*)

all of which are turned into:

(lambda (% %2 &rest %*)
  (list % %2 %*))

You may wish to substitute some fancy character for l:

(defun my-prettify-l-symbol ()
  (cl-pushnew '("l" . ?ƒ) prettify-symbols-alist))
(add-hook 'emacs-lisp-mode-hook 'my-prettify-l-symbol)
(global-prettify-symbols-mode 1)
