[idea]Compatible code for Markdown literary programming

Compatible code for Markdown literary programming. Just add a custom line comment character before each line of Markdown.

When previewing or converting a format, you only need to simply preprocess: replace the `\r\n\;` with `\r\n` (note: line comment character of Clojure is `;`)

For example:

```

;# Markdown literary programming

;## example01:

;```clojure

(defn f [[evens odds total amax amin] x]

  (let [[evens odds] (cond 

                       (even? x) [(inc evens ) odds]

                       (odd? x)  [evens (inc odds)]

                       :else     [evens odds])

        total (+ total x)

        amax  (max amax x)

        amin  (min amin x)]   

     [evens odds total amax amin]))

(reduce f [0 0 0 ##-Inf ##Inf] [5 6 8 -3 -9 11 156 6 7])

;```

;`=>[4 5 187 156 -9]`
