As others have suggested you need to use either Java's reflection or
Clojure's eval. Here's some examples:
Using reflection:
(let [obj "some string"
method (.getDeclaredMethod (class obj) "substring"
(into-array Class [Integer/TYPE]))]
(.invoke method obj (to-array [2])))
=> "me string"
If you want to know more about what you can do with reflection, consult:
http://java.sun.com/j2se/1.5.0/docs/api/java/lang/Class.html
Using eval (which will also work for dynamically calling Clojure functions):
(let [obj "some string"
fname ".substring"]
(eval (list (symbol fname) obj 2)))
=> "me string"
