I have looked at the docs for section and foreach many times, and
while I had a general intuition for how to use each, *when* to use
each hadn't become clear until I read this (and the previous mention
from maju(I think) about only using arrays indexed from 0...n-1).
Definitely a +1 for the note added to the docs.
In fact, I was primarily mislead by this note in the docs:
"The syntax for {foreach} is much easier than {section}, but as a
tradeoff it can only be used for a single array."
which, to me, implies that they serve the same purpose and can be used
on the same array types, with the caveat being noted.
