Hi, sorry about the delayed response — just had a new baby and have been in the hospital for a few days.
What I am trying to accomplish is be able to represent algorithms in a recursive format (which is often what comes naturally to me and seems cleaner and easier to understand) without the stack penalty. This is why TCO is baked into Scheme and CL, as the lisp people usually have this mindset. If you don't, that is fine and probably not worth an extended discussion. In my Haskell days, I represented most algs in some recursive format, though I found out there was usually some higher level abstraction available encapsulating the recursion. The "macro" I wrote seems to accomplish what I want, though I'm thinking maybe there are a few things in the macro code itself that could be improved. E.g., it seems a little weird throwing an exception, but I wasn't sure how else to do a non-local jump. And there is potential also for variable name collisions between the macro variables and the function that is passed in.
