would be the equivalent thing in Clojure?
I already tried the following but it doesn't seem to work
(sorry...i've been programming Clojure for only two days):

(:book s)

Thank you Mike and Jarkko for the detailed answer. It works as you described. :)

Does anyone know how I can replace a string with back-reference? I'd
like something like this:
(use clojure.contrib.str-utils)
(re-sub #"hello (\S+)" ", how are you \1?" "hello Jung")
=> "hello, how are you Jung?"
Basically I need the back reference \1 to evaluate to "Jung" in the
above case. Is
Thank you everyone for the tip. It works great. Using s/replace
instead of re-sub makes the code much shorter and easier to read.
Thanks,

program in Java and seems like an overkill for the String class.
Is there a better & easier way to add meta-data to strings?
