Clojure form to string

Is there a way to convert a Clojure form to a string? E.g. convert:

(and (f 1) (g 3))

to:

"(and (f 1) (g 3))"

You can do this:

(str '(and (f 1) (g 3)))

EDIT

In case you're not familiar with it, the ' ("quote") character is a reader macro character (more) that escapes code -- i.e. keeps it from being evaluated.

You could also set a variable:

(def x '(and (f 1) (g 3)))
(str x)

and then if you wanted to run the code you could eval it.

Alternativly if you don't know the form before hand you can do,

(defmacro to-str [f]
  (str f))

(to-str (and (f 1) (g 3)))

and get,

"(and (f 1) (g 3))"

=> (defmacro string-it [x] (str x))
#'user/string-it
=> (string-it (+ 1 2))
"(+ 1 2)"
