As the guys on stackoverflow already said, if think you need to use `eval` it is highly likely you are doing it wrong. That said, the last answer on stackoverflow seems to be correct. For example, when compiling classes for this code (ns testi.core) (let [noclo (fn [] "foo") s "foo" clo (fn [] s)] [(noclo) (clo)]) and disassembling them, you get: public final class testi.core$fn__2145$noclo__2146 extends clojure.lang.AFunction { public static {}; public testi.core$fn__2145$noclo__2146(); public java.lang.Object invoke(); } and public final class testi.core$fn__2145$clo__2148 extends clojure.lang.AFunction { java.lang.Object s; public static {}; public testi.core$fn__2145$clo__2148(java.lang.Object); public java.lang.Object invoke(); } So the function closing over s above has one additional constructor parameter, where the closed over value of s comes in to be set to the s field of the object.
