Example from Linguist:

;; # wisp

; Wisp is homoiconic JS dialect with a clojure syntax, s-expressions and
; macros. Wisp code compiles to a human readable javascript, which is one
; of they key differences from clojurescript.

;; ## wisp data structures

;; 1. nil - is just like js undefined with a differenc that it's
;;    not something can be defined. In fact it's just a shortcut for
;;    void(0) in JS.
nil ;; => void(0)

;; 2. Booleans - Wisp booleans true / false are JS booleans

true ;; => true

;; 3. Numbers - Wisp numbers are JS numbers
1  ;; => 1

;; 4. Strings - Wisp strings are JS Strings
"Hello world"
;;    Wisp strings can be multiline
"Hello,
My name is wisp!"

;; 5. Characters - Characters are sugar for JS single char strings
\a  ;; => "a"

;; 6. Keywords - Keywords are symbolic identifiers that evaluate to
;;               themselves.
:keyword  ;; => "keyword"
;;    Since in JS string constats fulfill this purpose of symbolic
;;    identifiers, keywords compile to equivalent JS strings.
(window.addEventListener :load handler false)
;;    Keywords can be invoked as functions, that desugars to plain
;;    associated value access in JS
(:bar foo) ;; => foo["bar"]


;; 7. Vectors - Wisp vectors are JS arrays.
[ 1 2 3 4 ]
;;    Note: Commas are white space & can be used if desired
[ 1, 2, 3, 4]


;; 8. Maps - Maps are hash maps, plain JS objects. Note that unlike
;;    in clojure keys can not be of arbitary types.
{ "foo" bar :beep-bop "bop" 1 2 }
;;    Commas are optional but can come handy for separating key value
;;    pairs.
{ a 1, b 2 }
;; In a future JSONs syntax may be made compatible with map syntax.


;; 9. Lists - You can't have a lisp without lists! Wisp has lists too.
;;    Wisp is homoiconic and it's code is made up of lists representing
;;    expressions. The first item in the expression is a function, being
;;    invoked with rest items as arguments.
(foo bar baz) ; => foo(bar, baz);

;; # Conventions
;; Wisp puts a lot of effort in making naming conventions tra
