A Great Idea

Hey /prog/, I just had a great idea. Let's use a double space (space space) as the delimiter between identifiers so we can have identifiers with spaces in them.

An example:
(defun  add to deck  (card  deck)
  (cons  card  deck))

It's like this is PHP.

Serious answer:
Adding $ or double spaces increase the amount of characters/keys you need to type and decrease readability. It would probably not require too much changes to the reader to implement, but why? Did you just start learning CL that you're so bothered by this? Escaping symbols with |...| is easy if that's what you want, no different from using (). Just rebind the || keys to something else if you use them to often, and make Emacs dim the || and () characters, so you wouldn't pay that much attention to them.
