I figured that x was being treated differently in some ways, because I always had to re-variabilize (is that a word?) x in a related context. I didn't realize that it was symbolic all the way through, though that would definitely be very inefficient.
However, I really hate using lambda or related constructions in the classroom because most students find it difficult enough to believe me that the loop definition isn't just magic, unless they have nontrivial programming background. Even very small helps in that direction really make things a lot easier for that demographic.
