1. create a new leinigen project:
lein new foo
2. modify foo.core.clj as follow:
(ns foo.core)
(defn format [] 1)
3. modify project.clj, add foo.core to aot:
(defproject foo "1.0.0-SNAPSHOT"
:description "FIXME: write description"
:dependencies [[org.clojure/clojure "1.3.0"]]
:aot [foo.core])
4. lein compile will throw exception

If I change the function name "format" to other things like "format1",
then compile will succeed.
