Fair enough, I was just responding to this: > A good Lisp programmer would never write such inefficient code. Why create a local function here when you can easily write a macro that expands into a loop with expr as its body? The nice thing about the call-with style is that it makes it easier to redefine your macro's functionality without recompiling all the call sites.
