I'm not sure of Rich's rationale for this. With `(do-some-stuff (~@#'some-ns/some-private-fn some ~@args)) you'd have the problem of embedding the function object in the code, but not with `(do-some-stuff (@#'some-ns/some-private-fn some ~@args)) which will just emit (do-some-stuff ((deref (var (some-ns/some-private-fn))) some arg1 arg2 arg3)) or the like. As for moving the cost of the deref to macroexpansion time, I don't think that can be done without embedding the function object, for obvious reasons. -- Protege: What is this seething mass of parentheses?!
