What he is trying to accomplish in his examples is vague indeed; the foreach loop and the C-style for loop are not functionally equivalent, even if the first was valid syntax. I suspect these are off-the-cuff examples to illustrate his question.

If you don't mind helping me understand, what are the two ways to parse his question? My own post shows how I parsed it. If that is one of the two, no need to rehash it.
