Thanks Marco, You're right, of course. I'm not using my function return. That being said, as far as I know, FPC can't optimize for tail recursion if I do use the function return in any way. So I didn't use the function return. Of course, you bring up a point of cleanness and style. If I don't use the function return, I should have made it a procedure instead of a function. Anyway, I learned from my forays into Guile that I don't yet have a good mental model of functional programming, hence my confusion.
