Hello,
I'm trying to create a "factory" method for Java classes, however I'm
doing something wrong.
(import '(java.util Dictionary HashMap))
(def *containers* { :dict Dictionary :hash HashMap})
(defn new-container
[type]
(new (*containers* type)))
(def d (new-container :dict))
The above gives me
Exception in thread "main" java.lang.IllegalArgumentException: Unable
to resolve classname: (*containers* type) (t.clj:6)

What is the right way to do this?
