;; If `c` is specified with a literal class name, this is a Java
;; class name.  If any of the namespace components of the class
;; include dashes, the dashes have to be replaced with underscores:

(ns foo-bar)
(defrecord Box [x])
(def box (Box. 42))

(instance? foo-bar.Box box)
;=> CompilerException java.lang.ClassNotFoundException: foo-bar.Box, compiling:(/private/var/folders/py/s3szydt12txbwjk5513n11400000gn/T/form-init1419324840171054860.clj:1:1)
