Clojure Newbie - Namespace Issues

Question

I study Clojure, and still I can not understand this little riddle, which, I am sure, is a ridiculous base.

I have this file:

(ns cloapp.core (:gen-class)) (defn -main "I don't do a whole lot ... yet." [& args] (println "Hello, World!") (println "Well Hi there, im a string !") (println "Why wont this work !") (myFunc "Hiya")) (defn myFunc [aVar] (println aVar)) 

If I try to run this with

 lein run 

He complains and says:

 Caused by: java.lang.RuntimeException: Unable to resolve symbol: myFunc in this context 

But if I remove the call to myFunc from main and do,

 lein repl cloapp.core=> (myFunc "Hiya !") Hiya ! nil cloapp.core=> 

Then I can call it. Why is this? I guess this has something to do with the namespace, but reading it I can't solve it.

The myFunc character is not yet defined, so main cannot find it. If you move the definition of myFunc over the main one, it will work.
