Yes, the comment gives an idea:

   ;; This notably allows '(' in Paredit to not insert a space when the
   ;; preceding symbol is one of these.

Basically if you don’t have it, when you type “#$(foo)”, Paredit inserts
a space before the opening parenthesis.

I think it also allows #$ to be highlighted in a special way.

HTH!
