I am trying to include some Groovy code at runtime, which is already on the 
JVM's classloader path. I have succeeded in setting the 
groovy.lang.GroovyClassLoader with Clojure's classloader as the Thread's 
contextClassLoader, but I'm having troubling getting (import ...) to work. 
I discovered so far that (import ...) prefers to use the 
clojure.lang.Compiler/LOADER if it's defined (and it is, in my project), so 
I tried the following:

(try
  (push-thread-bindings {clojure.lang.Compiler/LOADER 
(groovy.lang.GroovyClassLoader.)}
  ;GroovyCL defaults to use contextClassLoader as parent, which is the 
Clojure ClassLoader
  (import 'my_groovy_class)
  (finally (pop-thread-bindings)))

Note that I can successfully do (.. Thread currentThread 
getContextClassLoader (loadCLass "my_groovy_class")) once I've set the 
contextClassLoader.

What is the way to get (import ...) working so that I can manipulate 
my_groovy_class without resorting to forName/createInstance?
