When trying your code, I encounter the same problem ... ... but what is the compiler error telling us ?
[clojure.lang.AFn] is not a class ? ... maybe clojure.lang.AFn is ! Let's try (gen-class :name xg.gf.GenericFunction :extends clojure.lang.AFn ) (get rid of the square brackets !) It's sometimes weird how we just want to see what we want to see ! It took me almost 10 minutes to find what was just in front of me ! :-) -- Laurent 2009/2/19 mikel <mev...@mac.com> > > So I'm looking at improving the implementation of generic functions, > preparatory to making the library more generally available.
