Hi Jurjen, That wrapper for defn is something I was looking for in another post; I previously asked how I can inspect the definitions of my functions on the REPL. When I'm exploring stuff I'll be redefining many functions many times and sometimes I lose track things. I basically have to scroll around searching my REPL for the last definition. It sounds like you have a solution to this problem. It seems strange to me that Clojure doesn't support this concept natively. At some point the function definition is compiled into bytecode to run on the JVM, why not just automatically safe the original definition in metadata when this is done? Have you should about adding your wrapper code to Contrib?
