Yes, methods are not really functions. Thinking about them as closures over the object is a good way to go - you can see that analogy in play when you consider recur, which works with these methods, but could not rebind 'this'. The recur case sealed the deal in the decision not to include 'this' in the argument lists. Rich -- You received this message because you are subscribed to the Google Groups "Clojure" group.
