You're not making sense. There are two cases. Either you can directly edit the source code for the function, in which case you can substitute a modified defn; Or you cannot, but you can cause it to compile with a substituted version of one of the functions, macros, etc. that it references, in which case you can cause it to compile with a substituted version of the defn macro. What you're suggesting would only make sense if you have a source file with a function like this: 81 (defn foo [...] 82 (let [x (compute-something ...)] 83 (do-something x ...) 84 (calculate-whatever ...))) and you're able to edit lines 82, 83, and 84 but not line 81 (or whatever). But I can't see any plausible circumstance where that would be the case. -- You received this message because you are subscribed to the Google Groups "Clojure" group.
