user=> (defn foo [a] "") #'user/foo user=> (defn foo->foo2 [a b] "") #'user/foo->foo2 user=> (foo (foo->foo2 "a")) java.lang.IllegalArgumentException: Wrong number of args (1) passed to: user$foo (NO_SOURCE_FILE:0)
This example illustrates the problem. The exception indicates that the foo function has the wrong number of arguments. But it has one argument which is correct. It is actually the foo->foo2 function which should have two arguments but has one. I am using clojure 1.2.
