He was referring to the index. So was I, as in: Don't rely on the
index, because the size of the dictionary can vary, and therefore, the
index can vary, and therefore, the programmer must recognize that the
order of looping can vary. If you're referring to the actual order of
looping, then I and every good Python Guru (of which I am not one)
disagrees with you. If not, then you're confusing the different
meanings of "order" in this context.
