What you're describing sounds reasonable, but I've actually already implemented that in my own library: https://github.com/technomancy/robert-hooke I think that should cover what you're looking for. The basic add-hook usage is a bit more complicated than your example since the hook function has control over the target function's arguments and return value as well and can prevent the target function (or rather: continuation) from being called, but there are also append and prepend macros available if you are only interested in adding side effects. -Phil -- You received this message because you are subscribed to the Google Groups "Clojure" group.
