No, that's not what I'm saying-- that's a given and not relevant. What I'm trying to say is that trying to make "return" into a tail-calling form is clunky because it makes the control behavior of "return" different in different contexts. A tail return does jump-then-evaluate; a non-tail return does evaluate-then-jump. By contrast, with a lambda, there's no control effect involved in returning. A function simply returns the result of any expression in tail position-- no jumps in sight. No return, no jump.
