Yes. I thought it was clear that I understand this. I guess not.
My point is that foreach is doing something that isn't immediately
obvious. The same is true of your for loop, but to a lesser extent, IMO
(as I don't expect your for loop to ONLY read from $i).
I don't want to start a discussion on references. I'm just trying to
clear up a non-obvious case.
