Meanwhile thanks for your work that allow me to add metadata to functions : http://tinyurl.com/ygo65me.

I will update the article accordingly. But am I right to assume that any interface on clojure.lang is an extension point then? thanks Hmm.. you are right, Rich.

But am I right to assume that any interface on clojure.lang is an extension point then?
thanks

While the Obj abstract class may give you a free implementation of the metadata protocol, the right place to do extensions is actually just one level up - with the IObj and IMeta interfaces, which should support what you want to do without any hacks. >>or – better - have a Java interface that describes objects that can have metadata

Right, and the interfaces are already there! While the Obj abstract class may give you a free implementation of the metadata protocol, the right place to do extensions is actually just one level up - with the IObj and IMeta interfaces, which should support what you want to do without any hacks.
