Yeah. I think this example shows what I find unintuitive. If point is right 
before the first comma, and we transpose-sexps, it could end up swapping 4 for 
c * 7 - z * 2, which would rarely make sense in this context. Swapping b + 4 
with c * 7 - z * 2 would make sense here, imo. I believe this is not how you 
see it?
