Re: [BLOG] Once Upon A Class

When I tried some of your code in a default REPL (via the Clojure CLI), I don't see the same results. In particular: user=> (hash (.getContextClassLoader (Thread/currentThread))) 1865201235 user=> (hash (.getContextClassLoader (Thread/currentThread))) 1865201235 user=> (hash (.getContextClassL

Re: pre and post assertions, always in the meta data?
