Is there a better & easier way to add meta-data to strings?

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,

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
is the metadata

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

user> (defmethod .toString clojure.lang.PersistentStructMap [s]
