I'm not a Clojure expert so please correct me if I'm wrong but it
seems like you have to jump through similar hoops in Clojure?

Clojure 1.3.0
user=> (defn add1 [x] (+ x 1))
#'user/add1
user=> (add1 10)
11
user=> (binding [add1 #(+ % 2)] (add1 10))
IllegalStateException Can't dynamically bind non-dynamic var:
user/add1  clojure.lang.Var.pushThreadBindings (Var.java:339)
user=> (defn ^:dynamic add1 [x] (+ x 1))
#'user/add1
user=> (add1 10)
11
user=> (binding [add1 #(+ % 2)] (add1 10))
