Hi,

I have a simple question regarding identical?:
I understand that keywords with the same name refer to the same
object. So

(identical? :ab :ab)

returns true.
Now, if I do the following thing:

(identical? "ab" (str "a" "b"))

I get false, because my 2 strings are not the same objects even if
they represent the same sequence of characters.
Now, when I do this:

(identical? "ab" "ab")

I get true. Could someone explain me why these 2 strings are the same
object?
I think this topic was already adressed here:
http://groups.google.com/group/clojure/browse_thread/thread/c3d8d6101eb3a323/7a9f69ff900c2bab?lnk=gst&q=identical#7a9f69ff900c2bab
and here 
http://groups.google.com/group/clojure/browse_thread/thread/e43af17a0424b1cd
but I did not understand everything.

Thanks a lot for your help,

Regards,
Nicolas
